  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.

  Bye
  Oliver
