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).

I found a solution to the problem. There is no epkowa.conf in /etc/sane.d/ (or 
/etc/sane.d/dll.d/) Copying the default epcowa.conf file from the iscan sources 
made it work. Is this a Ubuntu bug or should the epkowa backend be able to 
work without the config file?

I can report it as a bug to Ubuntu if it is a Ubuntu bug.

Hello,

I haven't forgotten it. While cleaning code to add the XP200 and G2410, 
I 
found a couple of things that may help. Also while reworking my decoding 
scripts I found that they filtered some USB access. Need to dig it to find if 
it may fix something.

Stef

[sane-devel] why is the permittion to sanei_usb_open denied?

[Christian Wolf]

Hi,

this did not work:
I've checked that the user saned should be in the group scanner as I read the 
tutorial.

I've just done a reboot to ensure, that the /etc/groups gets reread.

I would also be wondering, if I could start saned as user sane in a separate 
shell using the debug parameters, but nut start ist as sane using xinetd.

Any other ideas?

Christian

adduser saned scanner

Reading /usr/share/doc/libsane/README.Debian.gz might also help.

[sane-devel] why is the permittion to sanei_usb_open denied?

[Christian Wolf]

Hello,

I want to use my scanner over the network using sane (server and client are 
running debian etch).

I did everything mentioned at http://penguin-breeder.org/sane/saned/ . As it 
did not work I also passed all the steps in the FAQ there.

In short:
I get the folowing message in my "log" (files in /tmp:
<...>
[plustek] usbDev_open(auto,) - 0x806fb58
[plustek] sanei_usb_open failed: Operation not permitted (1)
[plustek] open failed: -1
[plustek] sane_get_devices (0xbff42fe8, 1)
[plustek] sane_exit

In long:
I found the following out:
At the server the user sane is able to find the scanner using `scanimage -L`. 
Whenever I start the saned manually (using 
`SANE_DEBUG_PLUSTEK=8 /usr/sbin/saned -d8`) the scanner can be found by the 
remote client. When I start saned using xinet I get the message mentioned 
above. Even if I start saned manually as user saned it works.
Can you tel me what's going wrong here?

Thank you in advance
Christian Wolf

Both svn and cvs go through ssh on alioth; svn is also accessible via
the svn protocol, but no http...

perhaps you need

Weird.  Can you start a scan using the epson backend?

Well, at least the backend seems to be able to communicate with the
device.

No clue.  Can you do the same exercise with the epkowa backend and
attach the full log file.

For iscan-2.12.0 and later:

  SANE_DEBUG_EPKOWA=HEX scanimage -L 2> rx500.log

For iscan-2.11.0 and before:

  SANE_DEBUG_EPKOWA=127 scanimage -L 2> rx500.log

Hope this helps,

That thought has crossed my mind, but I'm behind a corporate firewall
that won't let me use CVS.  If the code repository were reachable via
HTTP(S) getting commit privileges would make sense but the way things
are they would be useless.

[sane-devel] demo patch for SANE 1 / SANE 2 coexistence

[stef]

Hello,

here's a variant to make SANE 1/SANE 2 coexist in the case of dynamic 
linking. dll.c is modified to search for backend with a soname of 2 first, 
and in case of failure, it searches backend a a 1 soname. This way if an 
out-of-tree backend in installed, it will still be usable by a SANE 2, and 
automaticaly searched and found.
To allow SANE 1 frontends using SANE 2 backends, there is still a sane2 
meta 
backend that is linked and installed with a 1 soname by the SANE 2 build 
system. This meta backend takes care of the SANE 1/SANE 2 API differences. I 
have also tested that copying this libsane-sane2.so.1 library as  
libsane.so.1 (overwriting the one from sane-1.0.19) allowed a SANE 1 frontend 
to detect and use SANE 2 backends installed without prefixing the device name 
with 'sane2'. So by tweaking the install process of SANE 2, SANE 1 
installation would be able to use SANE 2 backends without any change.

Regards,
Stef

[sane-devel] genesys/gl646 backend update

[stef]

Hello,

I'm currently progressing on adding support for the Strobe XP200. The 
latest 
development version now can do uncalibrated 75 dpi A4 color scans. The next 
steps are:
- handling of a scan area shorter than the document
- adding other dpi
- add a persistent calibration

On the G2410 side, I have coded registers setup for 300 and 600 dpi 
scans. So 
uncalibrated scan at these dpi should be doable. But since I don't have a 
device to test, issues are expected.

This unstable version is available at 
http://stef.dev.free.fr/sane/genesys .

Regards,
Stef

 Hi,

  can you enable epson2 only in your config and send
 me the whole debug output (privately if it's too big)?
