<P>
Hi folks and merry christmas to those who celebrate it!
<BR>
<P>Some time ago I had the problem of getting a SnapScan 1236S scanner to work
<BR>
with a 2.4.0-test kernel.
<BR>
It finally works thanks to Abel Deuring who did the work of contacting kernel
<BR>
developers, runnig tests and pointing me into the right direction.
<BR>
<P>Maybe I can help others using the same combination of hard- and software to
<BR>
get their scanner to work. These are the steps required to make it work:
<BR>
<P>- get kernel 2.4.0-test12
<BR>
- get latest reiserfs-patch
<BR>
&nbsp;&nbsp;(filename: linux-2.4.0-test12-reiserfs-3.6.23-patch.gz) and apply it
<BR>
- edit the file linux/drivers/scsi/aha152x.c (lines 1470+):
<BR>
<P>int aha152x_queue(Scsi_Cmnd *SCpnt, void (*done)(Scsi_Cmnd *))
<BR>
{
<BR>
#if 0 /* insert this line */
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(*SCpnt-&gt;cmnd == REQUEST_SENSE) {
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SCpnt-&gt;result = 0;
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;done(SCpnt);
<BR>
&nbsp;
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return SUCCESS;
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
<BR>
#endif /* and this one, too */
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return aha152x_internal_queue(SCpnt, 0, 0, 0, done);
<BR>
}
<BR>
<P>- configure, compile, install your kernel as usual and reboot to test
<BR>
- get sane-backends-1.0.4 and untar
<BR>
- get the most recent snapscan backend from snapscan.sourceforge.net
<BR>
- untar snapscan backend and copy files from the resulting snapscan/
<BR>
directory into sane-backends-1.0.4/backend. The existing - outdated -
<BR>
snapscan.* files will be overwritten. (This makes e.g. color scans work, btw.)
<BR>
- configure, compile, and install sane-backend as usual
<BR>
- get, compile, and install most recent XSane (0.68)
<BR>
<P>These aren't really step-by-step instructions and perhaps something is wrong
<BR>
(haven't really double-checked), but it should point you into the right
<BR>
direction.
<BR>
<P>Summary:
<BR>
- Linux 2.4.0-test12 + linux-2.4.0-test12-reiserfs-3.6.23-patch
<BR>
- patch to aha152x.c
<BR>
- sane-backends-1.0.4
<BR>
- snapscan-xxxxxxxx.tar.gz (I have snapscan-11282000.tar.gz)
<BR>
- XSane 0.68
<BR>
<P>Marcel
