I have a really nice SCSI HP ScanJet 4c which I haven’t used in a while, and YaST recognizes it (and the scanner scan test in YaST is also reported successful) but Gimp, Kooka, xsane, etc., report no devices available. These always used to work, so I’m suspecting a KDE problem of some sort. Any suggestions on troubleshooting would be appreciated! I’m trying to scan my homework for school!
OK, sort of getting an idea as to the problem:
How to configure your SCSI or USB scanner to work with SANE/XSANE from your regular user account | HowtoForge - Linux Howtos and Tutorials
PattiDesktop:/home/patti # sane-find-scanner
found SCSI processor “HP C2520A 3503” at /dev/sg0
Your SCSI scanner was detected. It may or may not be supported by SANE. Try
scanimage -L and read the backend’s manpage.
PattiDesktop:/home/patti # ls -al sg0
ls: cannot access sg0: No such file or directory
PattiDesktop:/home/patti # ls -al /dev/sg0
crw-rw---- 1 root root 21, 0 2010-02-26 09:45 /dev/sg0
PattiDesktop:/home/patti #
The trouble is, the scanner seems to belong to “root” - I couldn’t seem to change the group but I was able to add “rw” access to non-group members - it seemed to fix it - now kooka “sees” the scanner…
Yes, you need rw access to the scanner device to make kooka working.
