    Hi Bob,

    that has nothing to do with xsane, it is done in the backend.

    A typicall backnd.conf (here umax.conf) looks something like that:

            scsi UMAX * Scanner
            /dev/scanner

    The first line is for linux and this means the backend
    (there is a lib in the sane package that does it for all sane backends)
    searches all generic scsi devices (/dev/sg*) for vendor=id="UMAX"
    and type=6 (Scanner). The lib is intelligent enough to know that
    /dev/sg1 and /dev/sgb are the same.

    the second line "/dev/scanner" is for non-linux-systems. Here the user
    has to tell sane to which device-file the scanner is connected.

    Bye
    Oliver
