The first part of the SANE device name is the backend.

Maybe you need to edit snapscan.conf and enter the file name of the firmware file? See man sane-snapscan for details. > What may I try to work with this scanner? When you run "SANE_DEBUG_SNAPSCAN=255 scanimage -L" you or the snapscan developers may get a clue what's wrong. Bye, Henning
