Same problem here, using an Epson 2400 Perfection Photo flatbet scanner.
Weird - I remember it working once (xsane started up correctly) before
applying online updates. Can this be a bug introduced by an online
update?
lsusb finds it (connected to a USB hub):
Bus 004 Device 008: ID 04b8:011b Seiko Epson Corp. Perfection 2400 Photo
sane-find-scanner finds it:
found USB scanner (vendor=0x04b8, product=0x011b) at libusb:004:008
but xsane does not. 'sudo xsane' works fine however. "lshal" entry:

Why?
"ck-list-sessions" does not output anything.
This is on a Mac Mini G4 running Ubuntu 8.04 LTS PPC.
