Your milage may vary, but I've had great success with my 2940A and assorted
devices. I have a HP surestore CD writer (fast scsi), a Scanjet IIc (scsi),
an archive DAT autoloader, and a Micropolis 3387 (ultra scsi) all on the
same bus with no trouble. I even had a zip drive on this bus at one point.
Furthermore, the 3387ns is even improperly cabled (connected to the 25 pin
side of the HP scanner). I still get the 20mb/sec transfer rate and no
errors.

If it isn't working, you've either got a defective card, incorrect
configuration, stale bios or driver, horribly defective cables, or bogus
termination.
