Version: 0.44 (using KDE KDE 3.4.1) Installed from: SuSE RPMs OS: Linux suse linux 9.2 , was using prior kde version scanner (epson prefection 1200s, scsi) was running O.K scanning O.K in KDE 3.4 scanner is showing up correctly under YAST, and in the KDE control centre, Yast2 modules, under scanner. it shows as EPSON -perfection 1200, it shows SANE driver as epkowa. the device is showing as "dev/sg0" pressing the test button does not give any result. finally kookda is showing 0.44 release 2.6.8-24.16-default gcc 3.3.4(pre 3.3.5 20040809) in the kookda application selet scan device in hte settings menu , does nothing. no window nothing
O.K found the problem!! the rw flags on /dev/sb0 were changed by something during the install of KDE3.4!! after setting all +rw on all users for the device the problem went away. But This prevented the scanner being seen/used by KOOKA. ( how about some warning message !!! flags not configured etc) either the problem is in the sane library or KOOKA, but it is anoying that the scanner can be installed & configured from YAST (albiet as root), but then the system falls apart, due to lack of diagnostics from the front end.
Yes, a message like "You do not have permissions to access the scanner device (/dev/...)." would be appropriate.
If you can compile from source, please check out and try the SVN version at branches/work/kooka-kde3. This will report an error if SANE fails to access the device.
