[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Miles Wolbe]

Ran into the same scanner issue today with a Brother MFC-6490CW under
Ubuntu 18.04 (factory installed by Dell and fully updated before
attempting printer/scanner install). Found pdc's post on askubuntu.com (
https://askubuntu.com/a/1054065/314730 ) first, which linked to
staedtler-przyborski's symlink answer (
https://bugs.launchpad.net/ubuntu/+source/sane-
backends/+bug/1728012/comments/25 ). Worked a treat - thanks so much!

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

Hi Phil,

Łukasz will probably not see your question. But this fix is about Ubuntu
18.04, and no, the "Pre-released updates" option does not need to be
checked - the "Recommended updates" option in the "Updates" tab is
sufficient (and that one is checked by default).

To confirm that you got the fix you can open a terminal window and run
this command:

dpkg-query -W libsane1 libsane-common sane-utils

The version you should have is 1.0.27-1~experimental3ubuntu2.1

Also, please note that there are multiple possible reasons why your
scanner refuses to scan. This fix addresses one particular issue which
was a regression compared to Ubuntu 16.04.

To get help with your particular problem, please use e.g. Ask Ubuntu or
some other support resource as mentioned here:

https://ubuntu.com/support/community-support

This is a bug report intended to report, investigate and keep track of
bugs. It's not a support channel.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Łukasz Zemczak]

Normally I'd say we should wait for verification using a test case that
does not involve any workarounds, but seeing the actual bug-fix I think
it might be safe to release it with the testing it got already. This
seems to be a logical change.

Bug description:
  To the sponsor: Please upload to bionic using the attached sane-

  [Impact]

   * Starting with Ubuntu 17.10, Ubuntu changed the directory where sane
  dll looks for third party drivers. This configuration effectively
  broke backward compatibility for all existing third-party drivers.

   * A large swath of these third party drivers (most of them) are no
  longer supported by the OEM, so maintaining compatibility is
  important.

   * No open source replacement drivers are currently available, nor
  does the community have the resources to easily replace them.

   * This bug represents a substantial portion of the scanners in use.

   * This was working in the 17.04 release.  18.04 is an LTS release, so
  backporting is warranted for the 18.04 release.

  [Test Case]

   * Following the standard installation procedures for any of the
  affected scanner drivers results in the driver files being installed
  to /usr/lib/sane/, and sane looking for them in /usr/lib/x86_64-linux-
  gnu/sane.  When xsane is run, the scanner is not found.

  * Install the libsane1, libsane-common and sane-utils packages from
  bionic-proposed and confirm that it now finds drivers in
  /usr/lib/sane.

  [Regression Potential]

   * The proposed change is based on an upstream commit, and the patch
  is functional and stable in both 19.04 and 19.10. Low regression risk.

  [Other Info]
   * Third party sane drivers in previous version of sane were located under 
/usr/lib/sane/, however, the current version of sane on Ubuntu only looks for 
64 bit drivers under the /usr/lib/x86_64-linux-gnu/sane directory. /usr/lib64 
and /usr/lib64/sane are other directories old drivers are known to install 
files to.

  * The addition of symlinks alone does not appear to fix this issue,
  though it may make the scanner detectable. Changes to udev rules are
  also needed to allow proper communications to the scanners. A
  selection of workarounds, including working (though not ideal) udev
  rules for a number of scanners has been posted to the sane
  troubleshooting guide:
  help.ubuntu.com/community/sane_Troubleshooting#The_symlink_and_udev_tricks

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

Since I have an old Brother device whose drivers are installed via
brscan2, the proposed change (which adds support for drivers located in
/usr/lib/sane) doesn't really apply to me. But I worked around that.

The general preparations according to comment #232 are there, and in
addition to that I installed the libusb-0.1-4 package. However, I
dropped the ldconfig trick to make .so files in /usr/lib64 shared
libraries.

Now to the workaround. I added some symlinks to pretend that the driver
files are located in /usr/lib and /usr/lib/sane:

$ ls -l /usr/lib/libbr* /usr/lib/sane
lrwxrwxrwx 1 root root 28 jul  3 21:57 /usr/lib/libbrcolm2.so -> 
../lib64/libbrcolm2.so.1.0.1
lrwxrwxrwx 1 root root 31 jul  3 21:57 /usr/lib/libbrscandec2.so -> 
../lib64/libbrscandec2.so.1.0.0
lrwxrwxrwx 1 root root 13 jul  3 21:57 /usr/lib/sane -> ../lib64/sane

With that setup I first tested scanning with the sane-backends packages
in bionic-release. Result (simple-scan):

"No scanners detected"

Then I installed version 1.0.27-1~experimental3ubuntu2.1 of libsane1,
libsane-common, and sane-utils from bionic-proposed. After that I could
scan using either simple-scan or xsane.

Hello PeterPall, or anyone else affected,

Accepted sane-backends into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/sane-
backends/1.0.27-1~experimental3ubuntu2.1 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

Thanks @renbag. With your help I'm now confident enough to proceed with
the principal bionic change.

As regards support for the /usr/lib64/sane directory, I would like to
know if that change will be accepted in Debian before acting; please see
. So right now I'm waiting for an
answer to my question in that message.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[renbag]

I confirm that the packages in the proposed PPA allow to scan with a Brother 
MFC-440CN (brscan2).
I tried booting directly from a bionic USB stick and followed the steps listed 
on comment #232 (except adding a libsane rule, which is not needed in my case) 
and additionally installed libusb-0.1-4.
Thanks to Gunnar for the fix!

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

I made a new attempt with bionic, and yes!!

@renbag: You were absolutely correct, and it's brscan2 that requires the
presence of libusb-0.1-4. I think this explains it:

$ ldd /usr/lib64/sane/libsane-brother2.so.1.0.7 | grep libusb
libusb-0.1.so.4 => /lib/x86_64-linux-gnu/libusb-0.1.so.4 
(0x7f79f3e57000)

libusb-0.1.so.4 was used when libsane-brother2.so.1.0.7 was compiled, in
other words, and Brother should ideally have stated the libusb-0.1-4
package (which installs that .so file) as a depend in the brscan2 .deb
package.

So now I have been able to confirm that the proposed package for bionic
in the PPA makes a difference. Would still appreciate more feedback
before starting to look for a sponsor who can upload.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

@renbag: Tried that, but didn't help for me.

Actually it would have been weird if it had made a difference, since
sane-backends has been built with libusb-1.0-0-dev for a long time,
which make libsane/libsane1 and sane-utils depend on libusb-1.0-0.

I can scan with my MFC-240C on both 16.04 and 19.04.

With that said, and if you are still on bionic, it would be great if you
could install from the PPA and let us know how it goes.

I am having issues myself, but I think mine are related to running ubuntu
in a VM on Windows.

I got IT to set aside an unused desktop pc for me to load and run it on
(they say its now on my desk...).  Should have results tomorrow or Tuesday.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

The annoyance with Brother .deb files for scanner drivers installing in
/usr/lib64/sane has been mentioned multiple times above. The PPA now
includes a proposed fix of that for eoan, disco and bionic.

To be able to test myself, I breathed new life into my old Brother MFC-
240C. On disco it works fine, albeit after a few preparations - it's one
of those 'unsupported' devices, after all. These are the preparations in
my case:

* Install the driver brscan2-0.2.5-1.amd64.deb

* Add myself to the lp group:

  sudo adduser $USER lp

* Add a libsane rule for Brother:

  $ cat /lib/udev/rules.d/60-libsane-brother.rules
  ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

* Make the system know about .so files in /usr/lib64:[1]

  $ cat /etc/ld.so.conf.d/and-lib64-too.conf
  # for scanner driver installed by brscan2
  /usr/lib64

  and to update /etc/ld.so.cache:

  sudo ldconfig

* Reboot

[1]: The proposed fix makes sane find files in /usr/lib64/sane, but
brscan2 also installs .so files directly in /usr/lib64, and the fix
doesn't help for those. I could have created symlinks instead, but chose
to do it this way.

Anyway, after the reboot I can scan using simple-scan or xsane. On
disco, that is.

As regards bionic I have not been able to make it work. At all. Besides
the proposed package in the PPA, I tried to build sane-backends for
bionic using the eoan source. No problem with the build and install, but
still "No scanners detected" when trying to scan. I've tried it on two
computers.

So please let me know: Can you scan on bionic - at all? And if you can,
does the proposed package in the PPA make it easier for you?

If you are on 18.04 and affected by this bug, it would be great if you
could install from the PPA, test to find out if it makes a difference,

** Description changed:

- Many scanners can no more be used since sane has changed something: The
- 3rd-party plug-in the vendor provides as .deb package will still
- install. But the scanner is no more recognized.
+ [Impact]
  
- Scanners that are affected are(besides others):
-  - Epson Perfection V10
-  - Epson Perfection V1000
-  - Epson WorkForce GT-1500
-  - Brother MFC-8510DN
-  - Epson Perfection V33
+  * Starting with Ubuntu 17.10, Ubuntu changed the directory where sane
+ dll looks for third party drivers. This configuration effectively broke
+ backward compatibility for all existing third-party drivers.
  
- It is to note that the probability that the scanner manufacturers fix
- things others broke is below 100%.
+  * A large swath of these third party drivers (most of them) are no
+ longer supported by the OEM, so maintaining compatibility is important.

+  * Regression to previous working sane package often results in the

+  * The available patch is functional and stable in the 19.10 branch.
+ 
+ [Other Info]
+  * Third party sane drivers in previous version of sane were located under 
/usr/lib/sane/, however, the current version of sane on Ubuntu only looks for 
64 bit drivers under the /usr/lib/x86_64-linux-gnu/sane directory. /usr/lib64 
and /usr/lib64/sane are other directories old drivers are known to install 
files to.
+ 
+ * The addition of symlinks alone does not appear to fix this issue,
+ though it may make the scanner detectable. Changes to udev rules are
+ also needed to allow proper communications to the scanners. A selection
+ of workarounds, including working (though not ideal) udev rules for a
+ number of scanners has been posted to the sane troubleshooting guide:

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Gunnar Hjalmarsson]

To the extent this bug is similar to the linked Debian bug, it was fixed
in Ubuntu 19.04, so I marked it as "Fix Released". OTOH, in that case
there is a need to backport the fix to Ubuntu 18.04, and therefore I
added a bionic bug task.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[PeterPall]

@Luca-mg: What your computer sees is the following:
 - You attach a device whose USB ID doesn't match any udev rule => the device 
is accessible for the root user only.
 - then you as the root user start a program that uploads something to the 
device.
 - the device disconnects and
 - a new device connects, this time using an USB ID there is an udev rule for. 
This rule tells the device is a scanner. You are in the group "scanner" => You 
can use it without root rights.

What you need is an udev rule that tells the system that the USB ID your
device has before its firmware is uploaded is a scanner, too. As soon as
udev knows that this device is a scanner it will give you the necessary
rights to upload the firmware without being root.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[PeterPall]

Then the answer is simple: extend the udev file with the usb if of the
scanner without firmware so use will give you write access to this
device, too. Once that is done sane can upload the firmware, the scanner
can identify itself as the model you have bought and you can scan. Seems
like we should collect the Epson usb IDs somewhere...

@luca.mg: have you checked for firmware updates? My Brother DCP-L2550DW can
update from the web interface in the system tools/administration tab and
there have been a few updates in the last year.

@ PeterPall: regarding the Epson scanner, yes it could be the firmware
upload, the first root scan took time, I thought it was the scanner
warming up longer than usual and not catching up, but I allowed time and
it finally went through, so You may very well be right. I did not run
lsusb -v, just a plain lsub, but before the root scan the scanner was
detected as an epkowa driven unknown model, after the root scan it is
detected with the proper model name.

Re: [Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Chris Rainey]

Just a reminder to those of us using Brother DCP or MFP's: I repeatedly
find that the only way to properly install the printer and scanner drivers
is to use the "Installer Script"(i.e. 09/13/2018
(2.2.1-1)) provided on the model downloads page(see below) and to follow
the directions given _explicitly_(to-the-letter, no exceptions)! I've tried
to install a recently updated scanner driver(i.e. 01/21/2019
(0.4.7-1)) by itself as an upgrade to the currently installed one and even
re-ran the setup command(i.e. Brsaneconfig4 -a name=(name your device)
model=(model name) ip=xx.xx.xx.xx) for my network(Wi-Fi) DCP-L2550DW, but
it does not work that way. I can't stress, enough, the apparent need to
re-run the "Installer Script", exactly as shown--below, in order for
everything to work!


How to Install

Step1. Download the tool.(linux-brprinter-installer-*.*.*-*.gz)

The tool will be downloaded into the default "Download" directory.
(The directory location varies depending on your Linux distribution.)
e.g. /home/(LoginName)/Download

Step2. Open a terminal window.

Step3. Go to the directory you downloaded the file to in the last step. By
using the cd command.

e.g. cd Downloads

Step4. Enter this command to extract the downloaded file:

*Command: gunzip linux-brprinter-installer-*.*.*-*.gz*

e.g. gunzip linux-brprinter-installer-2.1.1-1.gz

Step5. Get superuser authorization with the "*su*" command or "*sudo su*"
command.

Step6. Run the tool:

*Command: bash linux-brprinter-installer-*.*.*-* Brother machine name *
e.g. bash linux-brprinter-installer-2.1.1-1 MFC-J880DW

Step7. The driver installation will start. Follow the installation screen
directions.


 When you see the message "Will you specify the DeviceURI ?",

 For USB Users: Choose N(No)
 For Network Users: Choose Y(Yes) and DeviceURI number.

The install process may take some time. Please wait until it is
complete.

Then perhaps uploading the firmware to the scanner can only be done as root, 
for some reason.
Does the output of susb -v change after scanning for the first time?

Hi Peter, if the above is addressed to me, the Epson scanner works for regular 
users after the first scan as root, I do not get the reason why, but this is 
it. 
Thank You for stepping in.

If the scanner can be found only by the superuser that might indicate
that an udev rule that allows scanner access for ordinary users is
missing. Or that this udev rule gives scanner access to an user group
you happen not to be part of...

Hi again, Epson Perfection 4490 Photo, new Ubuntu Mate 19.04 install,
iscan-bundle-1.0.0.x64.deb.tar.gz driver, make sure to add the line
'epkowa'to the /etc/sane.d/dll.conf file first; xsane gave a 'Access to
resource has been denied' message as a regular user, same with 'sudo
xsane' from a terminal, what I did is:

1) from a terminal enter 'sudo passwd root' and create a password for the root 
user, when done  
2) enter 'su root' and provide the newly created password, when root 
3) run 'xsane' despite the warnings AND scan a page (a previous attempt without 
scanning didn't work), after that, believe it or not, the scanner works, I do 
not really understand why and how, but this is it, though YMMV. 

Regards, Luca

Hi all, Brother MFC-1910W, new Ubuntu Mate 19.04 install, Brother
drivers from
https://support.brother.com/g/b/downloadend.aspx?c=as_ot&lang=en&prod=mfc1910w_eu_as&os=128&dlid=dlf006893_000&flang=4&type3=625&dlang=true
at first the scanner was not detected, my previous workaround involving
libsane-extras is not an option anymore, since the package has been
pulled out. What I did is:

1) created the file /etc/udev/hwdb.d/brother4.hwdb with the lines 
usb:v04F9p035D*
 libsane_matched=yes

2) created the file /etc/sane.d/dll.d/brother4 with the line 
brother4 

the scanner works with no further tinkering, creating symlinks and the like.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Mickaël Tessier]

Hello,
I am French, sorry for my English.
I was running Linux Mint 19 and I'm using a Brother DCP-J515W printer with 
scanner.
I do not know which tutorial I followed, but I could print and scan.
I wanted to install Linux Mint LMDE3.
With the Brother script or the demonipuch script, the printer works but not the 
scanner.
So I went back to Linux Mint 19.1, but same thing.
I wanted to back down by releasing Linux Mint 19, but same thing.
I ended up installing Linux Mint LMDE3 and trying to run the scanner.
After reinstalling me LMDE3, I used the Brother script, but the scanner was not 
recognized.
I executed these commands:

mickael@ascer-aspire:~$ sudo cp -R /usr/lib64/* /usr/lib/
mickael@ascer-aspire:~$ sudo scanimage -L
device `brother3:net1;dev0' is a Brother DCP-J515W DCP-J515W


And the scanner is recognized in Simple Scan, but it does not work.
Xsane does not recognize anything.

Thank you in advance

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Harald Braun]

I have with the multifunction printer Samsung CLX-3185N and Simple Scan
the following problem:

After starting Simple Scan, I can scan the 1st page; every other page no
longer. Error message: "Scan failed Scan failed to start."

What have I done so far:

Linux unified driver uld_V1.00.39_01.17.tar.gz downloaded from Samsung
through HP website and unpacked in my download directory.

Then the command

sudo ~ / downloads / uld / install.sh

called and installed the driver. There were no error messages.

Since the scanner was not recognized at the beginning, I created the
following links.

sudo ln -sfv /usr/lib/sane/libsane-smfp.so* / usr / lib / x86_64-linux-
gnu / sane

Now the scanner is found with sane-find-scanner and scanimage -L; but
that above Problem occurs now.

I tested the following before calling Simple-Scan:

haraldbraun @ Fulda: ~ $ lsusb | grep -e samsung
Bus 001 Device 005: ID 04e8: 343d Samsung Electronics Co., Ltd

haraldbraun @ Fulda: ~ $ sudo sane-find-scanner

Then I have the command in the terminal:

entered, Simple-Scan started.

The first start attempt of Simple-Scan fails.

The second start attempt succeeds; I then did the following activities:

- 1st picture scanned in (successfully)
- scanned the following image (failure, with o.a.
- Simple scan ends without saving
- tail finished.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[pen name]

I have a USB-connected brother printer/scanner MFC-7420, hooked up to a
desktop running xubuntu 18.04.1  The printer works but the scanner does
not.  I have tried pretty much every heck posted here and elsewhere but
to no avail.  Here's what I have done and the error messages I got.
Heads up:  I wonder what's the significance on the discrepency in (3)
below?

-
0) To install the drivers I following the instruction (+FAQ) on

https://support.brother.com/g/b/downloa ... all&os=128

including brother-udev-rule-type1-1.0.2-0.all.deb. The printer works, but not 
the scanner.
-
1) Xsane says

Failed to open device `brother2:bus2;dev5'
Invalid argument.

(sudo xsane gives the same error message). When I fire up simple-scan
(sudo or otherwise) it says

Ready to Scan
Brother MFC-7420

but when I click "scan" I got "Unable to connect to scanner".
-
2) scanimage -L
device `brother2:bus2;dev5' is a Brother MFC-7420 USB scanner

scanimage --test
scanimage: open of device brother2:bus2;dev5 failed: Invalid argument
-
3) lsusb
Bus 001 Device 002: ID 04f9:0180 Brother Industries, Ltd MFC-7420

[ Question: How come it says 001:002 when xsane complains about 002:005
?!! ]

[Question: According to
https://cromwell-intl.com/open-source/x ... ument.html
the command above should have listed "scanner" but as you can see it's not 
there]
---
4) I have copied files from lib64 to lib, such as
sudo ln -sf /usr/lib64/libbrscandec*.so* /usr/lib
Reboot but to no avail.
---
5) I added myself to the scanner group:
sudo usermod -a -G scanner (me)
Reboot but to no avail. I also tried

more /etc/group | grep -n scanner

and here's the output:
59:scanner:x:120:saned,(me)

6) I edited /lib/udev/rules.d/60-libsane1.rules following the heck in (#12 of)

https://easylinuxtipsproject.blogspot.c ... nters.html

Reboot but to no avail.

7) There is no "brother.conf" in /etc/sane.d

8) I used synaptic to delete all "brother" related files, reinstall the drivers 
in (step 0) above, reboot but to no avail.

9) I added the following two lines at the end of 
/lib/udev/rules.d/40-libsane.rules (Before the line "# The following rule will 
disable ...")

# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

Reboot but to no avail.

I'm at a lost on what to do. The scanner (again, it's USB-based, not wireless) 
worked until window, but I no longer have access to the window machine and I 
really need the scanner for work. Your help and advice is most welcome. THANKS!

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Diego Arimany]

Since 2017 until now (2019)

For EPSON's website provides Linux packages for scanners and printers as
(.deb, .rpm, or source) which are simple to install. In two steps (if
you have it on the network).

Step 1.
Go to EPSON Driver and Software Download Center 
(http://download.ebz.epson.net/dsc/search/01/search/)
Download and unpack the scanner driver (Image Scan, currently version 1.3.40)

imagescan-bundle-linuxmint-19-1.3.40.x64.deb.tar.gz

Then, run ./install.sh 
sudo ./install.sh

Step 2. (for a newtork scanner)
Edit the file /etc/sane.d/epson2.conf
Modify the line
net 192.168.xxx.yyy (to match your scanner IP)

That's it.
A full how to is at my website

[User]

I'm amazed that this bug has been opened for over a year and there is no
meaningful status update to be found.  I'd like to echo the questions
and comments posted by another user above at Comment # 197:

I am just a user, thus this post may sound naive but perhaps it gives a
different perspective:

Sane used to work until "something" was changed an now it doesn't work anymore 
for many people. My naive questions:
what was/is the benefit of the change?
do the benefits outweigh the created problems?
if not is there a way to fall back to the original situation?

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Chris Rainey]

All that was needed for my Brother DCP-L2550DW was to 'apt purge' the
manually installed drivers:

$ sudo apt --auto-remove purge brscan4 dcpl2550dwpdrv


Then *BE SURE* to use the Brother installer script:  
linux-brprinter-installer-2.2.1-1.gz

(or whatever your current version is from the support.brother.com
website, etc.)

Follow the instructions from the Brother download site and during the
script installation to-the-letter(EXACTLY)!

*** CAVEAT:  use the printer I.P. addy if on a LAN and _NOT_ the auto-
detected mDNS addy if you have an AT&T Fiber residential gateway such as
mine(BGW210-700) which has a ".local" domain hard-coded in the DNS. This
effectively kills mDNS(Avahi) broadcasts and so I'm not able to connect
to the printer using that system.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[luca.mg]

Hi James, glad it worked!

Hi all, on Ubuntu 18.04, with a multifunction HP printer/scanner I could
only run the scanner as root; it was not my system and the relevant
files were already /usr/lib/x86_64-linux-gnu/sane, don't know if they
were there by default or if the owner of the system put them in place.
Anyhow, I applied my workaround in post #73 and 74, changing file names
and vendor ID/product ID according to the HP driver, and the scanner can
now be run as a user. Hope this can be of help to anyone struggling with
HP devices.

Regards, Luca

@luca.mg Your suggestion in comment #157 worked! I had to install
libsane-extras (and libsane-common) using Synaptic Package Manager. Not
sure why those weren't already part of the install. I also added the
line "brother4" to the file /etc/sane.d/dll.d/libsane-extras. Now my
home wifi networked Brother MFC-J470DW scanner (brscan4) shows up and
works with XSANE and Simple Scan! Thank you!

I have a problem with a HP ScanJet 4370.  The scanner is correctly

PeterPall, thank you for your help. I opened LP: #1795725 for the
multiarch issue and forwarded the bug to Debian.

Is there a complete list of the udev rules collected so far that we
should consider adding to the Ubuntu packaging?

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Lloyd Hayes]

I also have this problem, but not with all Epson scanners. My
combination Artisan 837 printer/scanner works fine. But my Epson
Perfection V600 won't work. And after following the directions here I
ended up with 2 drivers for my Epson Artisan 837. But the Epson V600 is
still not working.

The V600 is used for high-res scans of prints and
negatives/transparencies. It naturally works on my old Windows computer,
which I want to get rid of. The reason for this V600 scanner is that it
can scan at over 12,000 dpi. It has a 2nd IR lens built-in for restoring
old images.

In the past, I have been able to get this scanner to work on my Linux
system. But that was in the past, and may have been before I upgraded to
the current Ubuntu Linux version...

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[PeterPall]

Making the library automatically look for plug-ins in all possible
places they can be found would be a great idea: This would mean that it
doesn't matter if the plug-in expects the library multiarch or not.

If I interpret the 0125-patch correctly it changes the path plugins are
found in instead of adding a second one.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Jeremy Bicha]

I understand why /usr/lib64/ doesn't work right now on Ubuntu (that's a
directory commonly used by Fedora and Red Hat distros).

I don't understand why /usr/lib/sane/ doesn't work according to the
comments here. When sane-backends was converted to multiarch, a patch
was added that I think was supposed to enable /usr/lib/sane/ to still be
supported.

https://jff.email/cgit/sane-backends.git/commit/?id=ac1cb335be
https://jff.email/cgit/sane-backends.git/tree/debian/patches/0125-multiarch_dll_search_path.patch

If that patch worked, then maybe it makes sense to just add /usr/lib64/
there too.

I don't have a scanner myself to test any of this.

Seiko Epson Corp. GT-F650 [GT-S600/Perfection V10/V100] doesn't work in
simple-scan in 18.04.1 LTS (Bionic Beaver). It worked without issues in
the previous LTS release. After extracting the firmware and setting up
the symlinks mentioned in this topic, at least XSane is working. I'm
using it now in a virtual machine in 16.04. :(

well, what is really mispackaged, is Epson's iscan 1.0.1 package which
places its .so backends into /usr/lib/sane , which is now went our of
sync with multi-arch library paths like /usr/lib/x86_64-*-*/sane ,
introduced in some of past Ubuntu release

I'm having the same problem with Samsung M2070 scanner, but thanks to
the information here I was able to patch it working. I linked the files
located in /usr/lib/sane (copied there likely by the samsung driver
installer) to /usr/lib/x86_64-linux-gnu/sane and now the scan works both
over the usb and the network.

'/etc/udev/rules.d/79-udev-epson.rules' and creating links to the
libraries ('ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-

[Wladimir Mutel]

Dear package maintainers,
as you see, 'epkowa' and some other Epson backends are clearly mispackaged.
Also, Epson USB device permissions should be set properly by udev
Let's see if this problem does have any chances to be fixed in Ubuntu 18.04 
before 20.04 is released

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Veron Rado]

Found a permanent fix for Samsung SCX-4600 and USB3 issue.

According to ArchWiki[1] systemd and dbus don't pickup environment variables 
set in ~/.bashrc.
That explains why the .bashrc fix didn't work.
So the solution I finally found and went for was number 2 in the list on 
ArchWiki here[2]

Using nano I edited /etc/systemd/user.conf.
I appended this at the bottom of it:

DefaultEnvironment=SANE_USB_WORKAROUND=1

Then I rebooted (I don't know how to get systemd to reload
/etc/systemd/user.conf with out rebooting)

And tah-dah! 
Simple scan and Xsane now work as normal.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Veron Rado]

Bit of a breakthrough :)

Launching simple scan and xsane via the terminal with the USB3 workaround[1] 
environmental variable works:
$ SANE_USB_WORKAROUND=1 xsane
Or
$ SANE_USB_WORKAROUND=1 simple-scan

The weird thing is I had previously set that variable by adding `export
SANE_USB_WORKAROUND=1` in my ~/.bashrc as outlined here.[2]

But that *did not work*.

It's only by chance I tried this.
So, apparently for the SCX-4600, the USB3 issue is the culprit.

Samsung SCX-4600 ID 04e8:3433 suffers from this issue too.
It worked fine on Ubuntu 16.04 and 16.10. 17.10 seems to have caused it.

Simple Scan doesn't find the scanner anymore.
Xsane finds it. Sometimes it doesn't. 
When it does find it, it fails to scan with "Failed to start scanner:Error 
during device I/O"

Scanimage finds it and works.
(It does crash with a segmentation fault trying `scanimage --test` but that 
might be a separate issue?)

I think the fix might be #80. But I don't have most ot the files listed:
- I don't have `/usr/lib/sane` directory at all.
- My `/etc/udev/rules.d` is empty.

Any pointers or tips are appreciated.

[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change

[Karl Kastner]

Samsung SCX-470x,04e8:3457 Samsung Electronics Co., Ltd, is affected as
well, the scanner is detected, but if a scan is attempted, the error
"Failed to start scanner: error during device i/o" is displayed. Then
the connection to the device is lost and I need to restart the device.

Rajasekharan workaround fixed the problem, thanks for posting it!

Clean install of sane and Epson drivers and reseating cables appears to
have taken care my problems with my Epson V500.

No. sudo scanimage -L gives the same result. It does not detect the
scanner. However schroot with chroot of Ubuntu 16.04 detects it
correctly. See below.

peter@andromeda:~$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

@Peter Bennett,

Let me make sure I'm following.  scanimage -L doesn't find the scanner,
but sudo scanimage -L does?

@Ken Wright
Thanks for the info. I installed gufw. I found that the firewall was disabled 
for "Home" and enabled for "Office" and "Public". I disabled it for all and 
rebooted. scanimage -L still does not find the Brother scanner.

@Peter Bennett,

If you've got Synaptic, start it and search for ufw.  I had it without
knowing.  I installed gufw, which is just a graphical interface to ufw
and was able to check the firewall rules.

@luca.mg
I tried what you suggested, and rebooted, but the scanner is still not found by 
scanimage -L

@Ken Wright
The network must be OK, because I can scan if I run under chroot in the same 
installation.

$Peterpall
I do not have gufw, or any firewall. the ports all should be open, and it does 
work under chroot so I don't think it is a network problem.

In my case the network problem also involved gufw being configured to
refuse all inbound connections: avahi's autodiscover requires you to
ope. the ports needed for bonjour.

[luca.mg]

@ Peter Bennet: hi there, I have a brother4 driven scanner too, all I
did was to run the latest brother installer and install the libsane-
extras package adding the line "brother4" to the file /etc/sane.d/dll.d
/libsane-extras to get control of the otherwise not detected scanner.
YMMV

@Peter Bennett,
I'm sorry, I don't know anything about network connections, but that's where 
your problem lies.  You've got the drivers linked, and the Epson rule, so once 
you get the network connection fixed you should be all right.  Sorry I can't be 
of more help.
