Thanks for the try Peter, but I had already tried that which was
carried through from a past version of sane which worked for me,
I just haven't used sane for awhile.

I seem to be having the problem of the scanner not being recoginzed 
by sane.

For sane-find-scanner I get:

[root at bugs:/etc]/% sane-find-scanner
sane-find-scanner: found processor "HP C2520A 3503" at device /dev/scanner 
sane-find-scanner: found processor "HP C2520A 3503" at device /dev/sg1 

Then:

[root at bugs:/etc]/% scanimage -L 
 
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). 

So if I try using xsane I get the same thing no scanner. With past 
versions the scsi was always the easiest one to use. I suspect a
problem with the scsi driver [Buslogic] with this kernel right now.

Thanks again,
