  The firmware is the software embedded in your scanner. When you insmod the
  ppscsi modules, it will be listed in your /var/log/messages. If not then try
  "sgcheck" or "cat /proc/scsi/scsi".
  i've been told you need at least firmware 1.60, because the versions before
  that one don't function very well.
  There was a mailing about firmware 1.60 which was made available.

  What I don't know about this is if it is possible to read the firmware and then
  make it available to other scanners. If that's possible i would want to give
  that a try, my scanner has firmware 2.10.

  The Microtek2 scanner i now have came with a cheap adaptec isa card. The
  microtek(1) scanner i had and still have was a parport model. It surprised me
  that the cables had the same 25-pin plug on the computerside and sort of the
  same 50-pin plug on the scanner-side. I tried it first with the scsi-card, and
  then with the parport cable of the old scanner. I'm lazy, so i didn't change it
  yet.
  The third port on my scanner has 15 pins, but i don't know what it is for, i
  have never used it.
