Just found the following:
Script started on Mon 03 Oct 2011 03:38:15 PM EDT
tom@dragon:~$ lsusb -s 001:005
Bus 001 Device 005: ID 04b8:011b Seiko Epson Corp. Perfection 2400 Photo
tom@dragon:~$ scanimage -L
device `epson2:libusb:001:005' is a Epson GT-9300 flatbed scanner

tom@dragon:~$ exit

As noted above I have been using scanimage from a terminal for a long
time. It has always been a little bit quirky. xsane also thinks it is
using a GT-9300 flatbed scanner. sane-find-scanner finds 0x04b8:0x011b
at 001:005 but does not report a model name.
Could this be my problem?
