Description David Keegan 2011-05-08 19:59:45 UTC

Description of problem:

Since I installed fedora I cannot scan with my Samsung CLX3175FN multi-function printer/scanner. When I boot Debian off a different partition the scanner works fine. The scanner is connected to a usb port on the computer.

Version-Release number of selected component (if applicable):

1.0.22 1.fc15

How reproducible: VERY.

Steps to Reproduce:

1. Switch on printer/scanner.

2. Run "sane-find-scanner". Scanner is detected as:

found USB scanner (vendor=0x04e8 [Samsung Electronics Co., Ltd.], product=0x342a [CLX-3170 Series]) at libusb:001:002

Conclusion: Scanner is functioning and is detected on the USB bus at the
OS level.

3. Run "scanimage -L". 

Actual results:

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).

Conclusion: sane backend libsane-xerox-mfp, is failing to handle the scanner though it is configured with the USB vendor and device codes.
 
Expected results:

device `xerox_mfp:libusb:001:002' is a Samsung Samsung CLX-3170 Series multi-function peripheral

Additional info:

I see the expected results above and the scanner works if I boot Debian from a different partition. Both Debian and Fedora 15 have the same version of the backend library libsane-xerox-mfp.so.1.0.22.

Workaround:

Place a copy of the Debian version of the backend library libsane-xerox-mfp.so.1.0.22 and the associated symbolic link in a directory accessible from
Fedora and add that directory to the beginning of LD_LIBRARY_PATH so it overrides the Fedora version of the library.

I don't necessarily recommend this workaround, but it does suggest that the problem is in the sane backend library.

Just because I'm a nitpicker ;-): you only verified that the USB part of the machine is talking to your computer with this. Functionality is a different kind of beef, verified e.g. by it working in Debian.

The Debian SANE packages already contain a patch from the upstream repository which I suspect to fix your issue. As I don't have your hardware, I've built a temporary scratch package containing the fix here:

http://koji.fedoraproject.org/koji/taskinfo?taskID=3059820

Please download the relevant packages from the build tasks for you architecture (x86_64, i686) and check whether this patch helps. Thanks.

If you can confirm that this patch fixes your issue, I'll incorporate the patch in the official packages.

You're correct.

Yes. The patch fixes my problem.

I note the patch rpms are "fc16". Will the fix make it into Fedora 15?

That's because I built the packages for Rawhide -- I'd have built them for F-15 if the bug was filed against it. Doesn't really matter anyway, I like to have bugs fixed in all releases if it can be helped, therefore I'll build fixed packages for all of them.
