    The simple way should be to put /dev/ugen0 into

    That is /usr/local/etc/sane.d/dll.conf?

    If your kernel scanner driver accepts this device that's ok.

    There isn't any manpage and As far as I know there aren't any options.

    Try with debugging enabled:

    SANE_DEBUG_1200UB=255 scanimage -L

    Maybe some incompatible USB handling between Linux and FreeBSD?
    Something concerning maximum size of a "block" that can be transfered
    at once? Just guessing...

    I'm pretty sure that the programmers didn't test on FreeBSD. I 'm
