I have the same problem on my SuSE10.0/AMD64 (no such problems in 
SuSE9.3/i586)The scanner is an Epson Perfection 2450 Photo/GT-9700. It 
won't run if I attach it to USB2, so it is on an firewire port.
Runs without problems when root, but no scanner is found as user.

sane-find-scanner reports:
found SCSI processor "EPSON GT-9700 1.05" at /dev/sg6
This is first time I see the /dev/sg6 - normally its either /dev/sg1 or 
I have tried to change permissions on the /dev/sg?, and then I can use 
the scanner as user, but after next reboot, the root-permissions are back.

Any idea how to change this permanentely? or will it be easier for me to 
change to a RedHat/Mandriva/???? than having SuSE to act in a proper way?

I have the sane-backends-1.0.17 installed - but I can't find any 
"libsane.rules" or "libsane.db" on my system!
The only libsane* files actually installed is the *.la and *.so*. The 
libsane.usermap reside in ~/sane-backends-1.0.17/tools/hotplug

Any help appreciated
