Hi Dieter,
Yes, thanks, here are the output of the commands:
On openSUSE 11.4 x86_64 Tumbleweed:
terje@linux-tiik:~> lsscsi -g
[0:0:0:0] disk ATA ST3500418AS CC38 /dev/sda /dev/sg0
[2:0:0:0] disk ATA ST3500418AS CC38 /dev/sdb /dev/sg1

[11:0:2:0] process EPSON Perfection1640 1.03 - /dev/sg4
----------
sane-find-scanner as normal user doesn't find the scanner, I have to run it
with root access and then it find the scanner as shown below:
terje@linux-tiik:~> sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

I also tested the same on the current 12.1 x86_64 M5 in dualboot on the same
machine, and got the same scanner access issue.
