    Hi,

    I'm having problems getting my Sharp JX-320 working with SANE under
    Linux. I had a read of README, README.linux, PROBLEMS, FAQ, sane-sharp(5)
    but I still can't see what's wrong.
    If anybody could help, I'd be very grateful.

    Plugged everything in, switched everything on.
    ./configured, maked, make installed...
    Issued following commands (as root)...

    # cat /proc/scsi/scsi
