That's exactly what happens here, too.<br>
|
|
The only difference is that I can't even unload the SCSI module (resource busy).<br>

Well, I haven't tried it too often, but in most, not all, cases it locks up.<br>
|
|

They actually seem to be accepted, but that shouldn't change the result anyway.<br>
|
|
<p>
|
|
Does it still lock up when you change the mode to Gray? Here, it still does,<br>
|
|
but not that often (much less often, indeed).<br>
|
|
How big is your SCSI buffer?<br>
|
|
Where does the scanner stop? (ruler on the scanner)<br>
|
|
<p>
|
|
I don't have any idea what could be the problem.<br>
|
|

Ciao, Michael<br>
