I verified this with a 2.2.10 kernel; I'm using it with the<br>
|
|
AVA-1505AE ISA card that came with a SnapScan 1236. I could not get<br>
|
|
it working with the 2.2.10 kernel, but replacing the `sg' driver<br>
|
|
(include/scsi/sg.h and drivers/scsi/sg.c) with the files form 2.2.5<br>
|
|
got it working.<br>
|
|
<p>
|
|
However, I still see some strange things happen:<br>
|
|
<p>
|
|
* During initialization (self test?) I see a lot of syslog messages<br>

(but then it's working):<br>

* Probably interesting fact is that with the 2.2.10 driver the same<br>

thing is happening (but then I can't access the driver, and the<br>

scanner LED continues blinking). But here the syslog messages look<br>

So it's 132 instead of 128 "expected" bytes...<br>
