Hi, <br>
|
|
<p>
|
|
I'm writing sane-support for the Tamarack SCSI scanner. I had the same<br>
|
|
problem: my NCR810 driver would report an "NCR DEAD" when I tried to<br>
|
|
scan a slightly non-trivial amount of data. <br>
|
|
<p>
|
|
Initially I increased the timeout to one minute. However nowadays, my<br>
|
|
driver simply reduces the scan-size to at most an inch at a time.<br>
|
|
The Tamarack takes less than 10 seconds to scan an inch, so there<br>
|
|
is no problem. This way I can run a standard kernel. (well almost).<br>
|
|
<p>
|
|
Mustec maintainers: This might also be applicable for the mustec<br>
|
|
backend....<br>
