I moved from Ubuntu 12.10 to 14.04 and have a Canon Canoscan LiDE 25. It worked fine with Xsane on 12.10.
Now I have the strange effect that I can use the scanner with scanimage all the time, but as soon as I use Xsane or any other frontend, it only produces black images (the scanner does not move at all). Occasionally, I can scan once (mostly preview) and the second attempt produces only black again. I can use scanimage afterwards and it is fine.
Seems to be a kind of reset problem to me, because when Xsane comes up and the scanner makes a short noise, the first scan works. Also when I scan, the scan arm does not return to the start position. Afterwards, it creates black images.
The reset problem occurs with other front-ends as well.
Suggestions welcome. Running the latest 1.0.25 sane version (compiled from source). Also the default install did not work before, hence I tried my luck with latest. Changed the cable too as suggested in other threads, but not change.
- libsane now: 1.0.25git, Kernel 3.13.0
- libsane was: 1.0.22, Kernel 3.2.0
Any debug help welcome.
