Re: [sane-devel] Re; scanning with LiDE series works under, Win, NOT under Lx

[Cedric Bhihe (毕生泰)]

A good day to you, Stijn and Allan and to all !

Stijn, I really don't fathom myself as a techie.
I just dabble in computin-related-things. At the same time I try to be 
thorough !

"Hartnäckig" is the word ("persistent" in English).

Good news !!
The ICM error disappeared upon uncheking the 'xsane' 's preference 
settings for "Enable color management".
I quit xsane and following Allan's suggestion I backed up and removed 
the directory ~/.sane/xsane before embarking in the error log recoding 
procedure.
I relaunched xsane and everything worked normally with LiDE 25. Both 
simplescan and xscan are back to nomal. I have not tested them yet with 
my HP 4400c but I don't expect any itch there.


I thank you all for your help, particularly Stijn and Allan who put up 
with my long "writes" and led me to the solution.

Re: [sane-devel] SANE; scanning with LIDE series works under Win, NOT under Lx

[Cedric Bhihe (毕生泰)]

Thanks a lot  Stijn and Allan ! I made "some" progress.

Here goes:
_Background_:
sane and libsane version 1.0.23 on Ubuntu 14.04.2
scanner Canon LIDE25 works under Windows  but not Linux
scanimage functions perfectly with scanner in identical conditions 
under Lx.


It turns out that just like for this post 
 
on askubuntu.com, I am running 'tlp' for power saving optimization. I 
applied the post's author's  solution by tweaking the 'tlp' config file, 
so that USB autodisable would not affect my LIDE25 (0x04a9:0x2220).
After applying the change to the tlp config file, I checked it from 
terminal:


$ cat -n /etc/default/tlp | egrep USB_BLACKLIST
   173#USB_BLACKLIST=": :"
   178USB_BLACKLIST="04a9:2220"
   187USB_BLACKLIST_WWAN=1

Result:
'simplescan' now works for the first time in 2 months or so (though it 
seems awfully slow to me).

'xsane' (the frontend I favor) gives me:
 "Error during CMS conversion: could not open scanner ICM profile."
The above error message appears when I launch 'xscan', when I try to 
change any setting and when the scan is over.
Trying to scan, the scanner goes through all the moves at a normal 
speed) but scan everything blank.


So I tried four things:

*1)* Following another post , I 
created the new rule:

$ sudo vi /etc/udev/rules.d/40-libsane.rules |
ATTRS{idVendor}== "04a9", ATTRS{idProduct}=="2220", 
ENV(libsane_matched)="yes"|||

$ sudo chmod 644 /etc/udev/rules.d/40-libsane.rules

'simplescan' 's behavior is unchanged. It scans in mode gray, color. All 
good.
Relaunching 'xsane' I did NOT get any more error messages. However, 
although 'xsane' launched and allows the scanner to do previews and 
scans without complaining, EVERY preview or scan comes out blank, even 
after reboot.



*2)* I set my debug log level to 80 (don't really know what level 
between 1 and 128 I should use here)

$ SANE_DEBUG_SANEI_USB=80
$ export SANE_DEBUG_SANEI_USB

However I know neither where log files are located, nor how I should 
post them for review.

Perhaps s.o. can help me with hints on that.

*3)* I edited the sane.d genesys.conf file to include a reference to 
Canon LiDE 25

& sudo vi /etc/sane.d/genesys.conf
# Canon LiDE 25
usb 0x04a9 0x2220*

4)* Following Allan's suggestion I checked whether my bios/kernel relies on

xhci_hcd

It does not, apparently. It seems to rely on 'ehci-pci' as seen from the 
command


$ dmsg | tail

ran upon plugging my LiDE 25 scanner onto the 7-1 usb port.

 I believe I do not have any USB3 issue. I simply do not have USB3 
ports, just two USB1.1 and two USB2 ports.


Nevertheless knowing that power management is also effected at kernel 
level, via the usbcore.autosupend parameter and  I did:|


$ modprobe usbcore autosuspend=-1

|That did not have any benefical effect and I reversed the action:
|
$ modprobe usbcore autosuspend=2|

Can somebody further suggest something ?
Also I need help with the debug log files. Where are they located and 
how do I post them ?

Thanks.

[sane-devel] SANE; scanning with LIDE series works under Win, NOT under Lx

[Cedric Bhihe (毕生泰)]

A good day to everybody.

I keep reading about flatbed scanners from Canon (in particular of the LIDE
series) not working when USB-plugged in under Linux but working fine under
Windows. I have exactly the same problem with a LIDE 25 and an HP 4400c
scanner.

Yes, both scanners are old but they are in excellent condition, (very low
mileage + many years forgotten somewhere in their original packing).  Both
work flawlessly under legacy Windows XP as well as under Win 7 on different
machines, including one that runs a dual Lx/Win boot.

As far as 'sane' front-ends go, I downloaded and installed two from the 
Ubuntu

Software Center and tried them repeatedly.
- simple scan 3.12.1
- xsane 0.998 whose author I even contacted, Oliver Rauch, hoping for 
pointers.

Unfortunately I got no answer.

Nothing seems to work under Linux with a 'sane' based gui for those two 
scanners,

BUT:
-1- it was not always the case. Up until about 8-10 weeks ago, xsane 
used to work

flawlessly for me. Nothing in my system (hard and soft) changed since then,
apart from regular stable and security related updates as provided by 
Canonical.
-2- I can scan w/o an itch from my Ubuntu terminal using 'scanimage'. I 
do that

on a daily basis with no errors.

I already wrote about that here, about 40 days ago, and got a resounding 
silence

 for an answer. No idea why.

Anyway I believe this is completely unrelated to the USB3 issue that is 
now widely
publicized. This probably has to do with some change in the kernel AND 
the way
the two afore mentionned 'sane' based gui packages handle communication 
with

the scanner or the daemon that handles USB comm. or some' else.
Something happened about 8 to 10 weeks go and I don't know what it is.

Since I am no techie, I am stuck, but at least 'scanimage' on terminal 
works.

The downside with scanimage is despite all available options
- no preview is available (pre-processing),
- no collating batch (multi-page) scans (post-processing) is possible,
- there is no saving scans directly as pdf (post-processing).

[sane-devel] Problems scanning with front-ends on Canon CanoScan LiDe 25

[Cedric Bhihe (毕生泰)]

Greetings !
Before about 2 months ago, my Canon LiDE25 worked perfectly well in my 
Ubuntu Desktop 14.04.x environment . It had done so

Then all at once I found myself battling with a scan malfunction.
I tried using "Xsane Image scanning program", then "Simple Scan" then 
"gscan2pdf" on an up-to-date installation of Desktop Ubuntu 14.04.x. HW 
is an old HP Intel 8510w with 3 USB ports. All ports were tested, 
function well and behave the same.


Description:

1 - plug the flatbed scanner in any USB port
-- nothing happens (no noise, no movement).

2 - from terminal:
>  scanimage -L
device `plustek:libusb:005:004' is a Canon CanoScan LiDE25 flatbed scanner
-- correct detection

3 - in the Plustek-SANE back-end configuration file, 
/etc/sane.d/plustek.conf, I inserted:

   # for Canon CanoScan LiDE 25
   [usb] 0x04A9 0x2220
   device /dev/usbscanner
although later positionned in the same file, and in the same [usb] 
section, I discovered

   device auto

4 - from terminal:
> scanimage -x 100 -y 200 >output-trial.tiff
or simply
> scanimage >output.tiff
-- both produce a correct although low res color image _every_ single time.

5 - when using either "Xsane Image scanning", "Simple Scan" or 
"gscan2pdf",  the response ot Canon LiDE 25 becomes comletely erratic.
Either it does not respond at all or responds once every 20 trials with 
a correct scan and then not at all.  Almost a complete no go ! Very 
surprising given that up until about two months ago, everything worked 
smoothly.
When clicking repeatedly on the scan button of any of the above 
mentionned Sane grafical front-ends, a message can appear saying that no 
scanner is detected. It does not always appear. More often there is 
simply either no response or null data acquisition without an actual 
physical scan, i.e. the raster-arm does not move.  Null-data 
acquisitiopn translates as a uniform black or grey or white preview 
(when preview is available).
Sometimes after the only possible first scan , the scanning raster-arm 
does not come back to its home position. The scanner is therefore not 
available anymore. Making it come back, involves quitting the frontend, 
unplugging the scanner, plugging it in again. and relaunching. This 
never happens from terminal.


I have read past posts posted on the subject during the past 10 weeks, 
in particular those of lszkclek at yahoo.com 
/

//http://lists.alioth.debian.org/pipermail/sane-devel/2015-March/033215.html
/and that jsmeix at suse.de 


http://lists.alioth.debian.org/pipermail/sane-devel/2015-March/033220.html
but somehow I doubt that this is a USB port problem as everything works 
well from terminal , plus I don't deal with a Suse type distro. Ubuntu 
relies on "deb" packages not "rpm".



I am stumped.
Is this rather a front-end problem ? It sure looks like it.
