    Hi Derek,

    the source of these rumours is me.
    I do not know if this works. I see a small chance and it would
    be interesting if someone would test it.

    The reason why I think it could work is the following:
    USB scanners do not have a processor, the use a simple ASIC.
    Because of this they are not able to use the SCSI protocol
    wich needs much more "intelligence" than the ASIC has.
    The Astra 2200S has a processor and so it is possible that
    the SCSI protocol also is used for the USB connection.

    As far as I know nobody every tried this or succeddes with it.

    If you find out anything about that, let me/us know.
