<EM>&gt; Modern versions of SANE detect whether you have SCSI generic and SCSI
</EM><BR>
<EM>&gt; working in find-scanner. You were asked to run find-scanner already, what
</EM><BR>
<EM>&gt; if anything did it have to say about SCSI generic (sg)?
</EM><BR>
<EM>&gt;
</EM><BR>
Well, I've been gone awhile till I got this figured out, but my scanner is
<BR>
up and running now.
<BR>
<P>In short, the precompiled kernel, which came with my LinuxPPC distribution
<BR>
(2.2.15) lacked direct sg support. Meanwhile, the source and modules which
<BR>
came on the disks are for 2.2.14, meaning the sg module was too old for the
<BR>
kernel I had.
<BR>
<P>Therefore, this exercise, in getting sane to work, turned into a course in
<BR>
&quot;Building Your Kernel 101&quot; (all new stuff for me). There turned out to be
<BR>
problems with the 2.2.14 kernel tree, mainly a 'missing directory' error, so
<BR>
I downloaded a 2.2.15 tarball that I WAS able to compile, specifying sg
<BR>
support. After booting from the new kernel, the scanner ran beautifully.
<BR>
<P>Thanks to all who helped me, both on the list and privately.
