First, make sure you have sg (SCSI generic) support in your system. It
is almost always built as a module. Also, make sure the scanner is being
detected by your SCSI adapter before Linux starts booting. Then check to
see if Linux is detecting it.

Once you verify the scanner is being detected, check the permissions as
mentioned in the relnotes:

"You need to make sure all of the /dev/sg* devices are read/write
accessible."
