Let's compare notes - I've got the same model and make working fine,
even for regular users.
(Redhat 9.0, sane-backends 1.0.12, kernel 2.4.20-18.9 (RH Errata vendor
kernel))

I'm not using the scanner.o module, never had much luck with it. libusb
0.1.6 works well enough for me.

defender:~:$ scanimage -L
device `gt68xx:libusb:001:002' is a Genius Colorpage Vivid3xe flatbed
scanner

Have you tried actually scanning an image? I really don't see any
permissions or access related problems. (I had to remount my
/proc/bus/usb devmode=0666 to enable user access, but that might be a
Redhat-only issue. YMMV.). You can at least find the scanner as a user,
which is encouraging.

What happens when you run "scanimage > out.pnm"?

Do you see lots of "bulk_timeout"-like messages among your syslog
entries when you try and scan or run xsane/kooka?

There was a small patch for the gt68xx backend back in late April that
addressed a USB timeout issue (it saw the scanner but subsequent
operations seemed to overwhelm the USB bus on many systems).

Check the archives for this, apply and recompile if you haven't got it.
It worked spectacularly well for me.

> thanx for your help! :)

Cheers,
Michael Fleming.

(PS Henning, the colour handling/matching on this backend and the Genius
Vivid3XE seems to be OK in my tests/experience, I'll put some more
examples if you wish)
