<EM>&gt;&gt; I have a problem using sane-1.0.2. I have compiled with debug enabled

<EM>&gt;&gt; sane takes a long time to complete its job (which is to list the

<EM>&gt;&gt; What seems to be the problem here?
</EM><BR>
<EM>&gt;&gt;
</EM><BR>
<EM>&gt;&gt; I know sane-1.0.1 worked (and still does) fine with this SCSI card
</EM><BR>
<EM>&gt;&gt; (sym53c416) and this scanner (HP PhotoSmart Photo Scanner).
</EM><BR>
<P><EM>&gt; Bernhard,
</EM><BR>
<EM>&gt; There is an linux kernel issue with the sane_1.0.2/sg_2.1.38/sym53c416
</EM><BR>
<EM>&gt; combination. Trying going to:
</EM><BR>
<EM>&gt; <A HREF="http://www.torque.net/sg">http://www.torque.net/sg</A>
</EM><BR>
<EM>&gt; and get the sg_2.1.39 tarball from the table and building it. That should
</EM><BR>
<EM>&gt; cure your problem. [If you look in your log (/var/log/messages) you will
</EM><BR>
<EM>&gt; probably find some nasty oopses corresponding to those pauses.]
</EM><BR>
<P><EM>&gt; Please tell me if that cures your problem.
</EM><BR>
<P><EM>&gt; For those it don't like rebuilding their kernel or modules, defining the
</EM><BR>
<EM>&gt; environmental variable SANE_SG_BUFFERSIZE to 32768 will also
</EM><BR>
<EM>&gt; fix this problem.
</EM><BR>
<P><EM>&gt; Doug Gilbert
</EM><BR>
<P>This worked! Both suggestion actually worked. First tried the
<BR>
buffersize change and it worked. Then I patched my kernel and rebooted
<BR>
and the new sg module also worked.
<BR>
<P>Thanks!
<BR>
<P>In /var/log/messages there were no indications of anything not working
<BR>
for the scsi system. The only scsi messages occured when I inserted
<BR>
the scsi modules (device detected and stuff like that, no errors).
<BR>
<P>Thanks again.
<BR>
<P>regards,
<BR>
<P>Bernhard Ege
