  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

who can help me to get my epson working?

[hendrikL]

well maybe you need an external driver:
http://www.sane-project.org/lists/sane-backends-external.html

Your scanner is listed to be fully supported.

Above the epson table is a link too:
http://avasys.jp/eng/linux_driver/

For the installation of the driver you have to search by your own.
I did not have a firewire scanner, but maybe it helps.

modprobe sg was the solution of this problem.

I've put the line "sg" in /etc/modules and everything is alright now.

But I think normally the module sg should load automatically.
Is this a bug? I don't know.
