Hi Peter,
I have the same scanner and went through the same trouble as you. While connected to SCSI: no problem, while connected to USB random freezes. I solved the problem by using libusb only. My advice: either recompile the kernel without scanner support or move 'scanner.o' outside the module path. Quick test: after powering on the scanner, do a 'rmmod scanner' and then do your test (make sure that scanner.o doesn't get loaded).

Cheers,
Klaus
