Comment 18 for bug 121082

I also am having permissions issues with an Epson Perfection 2450 Photo scanner.
I have two scanners attached, both are IEEE1394 interfaces. The Nikon Coolscan works fine and is seen by xsane and vuescan.
The problem is with an Epson Perfection 2450 Photo which is not seen by either app.

Executing "gksudo xsane" works with the both 2450 and Coolscan scanners.

Executing xsane from the menu under my userid does not work with the 2450.
Executing xsane from the menu under my userid works OK with the Coolscan

Executing "sudo sane-find-scanner" returns:
found SCSI processor "EPSON GT-9700 1.05" at /dev/sg5
found SCSI scanner "Nikon LS-4000 ED 1.10" at /dev/sg6

Executing "sane-find-scanner" returns only:
found SCSI scanner "Nikon LS-4000 ED 1.10" at /dev/sg6
