xscanimage can't find device...

["Johnny Ernst Nielsen" <j.e.nielsen@iname.com>]

Both xscanimage and xsane say they can not find a device.
Am I missing some setup?

Debian 2.2r3
Mustek MFS-6000CX on an AHA1542 SCSI controller.
find-scanner finds the scanner on /dev/sg1 and on /dev/scanner
/etc/sane.d/mustek.conf looks like this:

#--- Global options ---
option strip-height 1
#--- SCSI scanners ---
scsi MUSTEK * Scanner
option lineart-fix
scsi SCANNER
option lineart-fix
/dev/scanner
option lineart-fix

I also tried /dev/sg1

Results of command line commands:

johnny@nalle~$ xscanimage

xscanimage: no devices available.
Gtk-CRITICAL **: file gtkmain.c: line 534 (gtk_main_quit): 
assertion `main_loops != NULL' failed.

johnny@nalle~$ xscanimage /dev/scanner
(Window pops up saying: "Failed to open device '/dev/scanner': 
Invalid argument.)
(When I press [OK] the command line says...)
Gtk-CRITICAL **: file gtkmain.c: line 534 (gtk_main_quit): 
assertion `main_loops != NULL' failed.

Any ideas?

Cheers :o)
