    Hi Abel, hi Stephen

    the inquiry of umax scanners is about 160 bytes.
    I don`t know what the scsi-driver does.
    The umax-backend sends its own inquiry commands
    and expects that the scsi-driver does not cut the
    inquiry length. If the driver does cut the lenfth
    to less than about 180 bytes the umax backend may
    get in trouble.

    This has nothing to do with sane, it is a scsi driver
    problem. I suggest to inform the author of the scsi driver
    and/or to buy a good scsi controller card.
