Hi,

I'm writing sane-support for the Tamarack SCSI scanner. I had the same
problem: my NCR810 driver would report an "NCR DEAD" when I tried to
scan a slightly non-trivial amount of data.

Initially I increased the timeout to one minute. However nowadays, my
driver simply reduces the scan-size to at most an inch at a time.
The Tamarack takes less than 10 seconds to scan an inch, so there
is no problem. This way I can run a standard kernel. (well almost).

Mustec maintainers: This might also be applicable for the mustec
backend....

Roger.
