<P>The problem was here. The aha152x.c driver filtered out request_sense
|
|
<BR>
|
|
commands and always returned 0 on them. (At least that's my layman's
|
|
<BR>
|
|
understanding of the problem.)

<P>int aha152x_queue(Scsi_Cmnd *SCpnt, void (*done)(Scsi_Cmnd *))

|

<BR>
|

SCpnt->result = 0;

|
|
<P>Removing everything but the "return" line fixed the problem :)
|
|
<BR>
|
|
<P>Thanks to Marcel Martin for the fix :)
|
|
<BR>
|
|
<P>P.S. Judging from a quick look, a few other drivers may have the same
|
|
<BR>
|
|
problem. aha1542.c at least seems to be affected. I have no such card, so
|
|
<BR>
|
|
can't test.
|

|
|
<P>The scanner works fine now, whee :)=

The UNIX philosophy basically involves giving you enough rope to
|

hang yourself. And then a couple of feet more, just to be sure.
