Hi,
|
||
<BR>
|
||
<P> I've been using my Fujitsu M3091 SCSI scanner with my self-made
|
||
<BR>
|
||
driver as the only device on an Adaptec 2940 until now with no
|
||
<BR>
|
||
trouble. Now I've upgraded the system - another mainboard etc., but
|
||
<BR>
|
||
the controller and scanner are still the same. Rebuilt sane and all,
|
||
<BR>
|
||
but now when I try to scan documents, the paper is fed through the
|
||
<BR>
|
||
scanner at an unusual speed, and the resulting data stream contains
|
||
<BR>
|
||
only garbage. (The scanner does seem to transfer the correct amount of
|
||
<BR>
|
||
data, and it does seem to respond correctly to the various SCSI
|
||
<BR>
|
||
commands as per SANE_DEBUG_... output).
|
||
<BR>
|
||
<P>I have noticed that during startup, the system reports that the
|
||
<BR>
|
||
Adaptec SCSI adapter is using the same IRQ as the AGP video
|
||
<BR>
|
||
controller.
|
||
<BR>
|
||
<P>Is it possible/likely that an IRQ problem results in a behaviour like
|
||
<BR>
|
||
this, i.e. simple scanner commands work fine but when reading scanned
|
||
<BR>
|
||
data you only get garbage? And, while slightly off-topic - with
|
||
<BR>
|
||
neither the Adaptec nor the graphics adapter having any hardwar or
|
||
<BR>
|
||
software configuration options, how can I avoid the IRQ conflict?
|
||
<BR>
|
||
<P>Bye
|
||
<BR>
|
||
Frederik
|
||
<BR>

||
<P><PRE>
