Oh, not such a great problem!
I only say it to everyone who sends big mails so I can keep the
mail-size small! There is no great problem if some people do send
such mails, but if I do not say anything a get a lot of such mails!

Hm.
Is it an active terminator? If no, get one, you need an active one
for an ultra scsi card. It does not help to reduce the speed of the card
because the gradient of the signals is not changed!
Test also the configuration of the scsi card:
- try to reduce speed from 20/40 mhz (ultra/ultrawide) to 10/20 mhz (fast/fastwide)
or 5mhz(asyncronous).
- disable disconnect/reconnect
- disable tagged command queeing
I know you already did this for one scsi id,
if possible , do this for the full card and not only for the scanner device.
If all does not help - do you have the umax scsi card uds-11?
It is a very bad card but for some tests ... (read the umax.faq on my homepage for
more info
about that)!
May be you have a frien wit an ncr53c8xx scsi card or a good adaptec card, could be
worth to try with an other (not ultra) scsi card!
