<BR>
<P><EM>&gt; &gt; At first, my version information: sane-1.0.2-58 on SuSE 6.2 / 7.0
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Could you please send the output (dbg.log) of
</EM><BR>
<P>On the way to your private email address.
<BR>
<P><EM>&gt; You may remove (comment) the USLEEP entry. This should give the best
</EM><BR>
<EM>&gt; performance while blocking the whole system. But I fear it won't help much.
</EM><BR>
<P>I tried but got the same result. I put a comment block around the USLEEP
<BR>
portion and did a &quot;make modules&quot; &quot;make modules_install&quot;. I saw, that the
<BR>
module was compiled again. Then I rebooted the machine to make sure and tried
<BR>
another scan. It was no difference.
<BR>
<P><EM>&gt; If you have a fairly recent SANE (1.0.3 or a recent CVS version) the Mustek
</EM><BR>
<EM>&gt; backend is able to increase the SCSI buffer size and will use 1024 kB as a
</EM><BR>
<EM>&gt; standard. The bigger size has some effect on the speed.
</EM><BR>
<P>Maybe I should get a new source tree, then? How do I adjust the amount of
<BR>
memory?
<BR>
<P><EM>&gt; &gt; the 50 pin external connector with a 50 - 50 SCSI II cable, nothing works
</EM><BR>
<EM>&gt; &gt; anymore. The termination jumper on the card doesn't help.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; With both devices on the external and internal bus the terminator should be
</EM><BR>
<EM>&gt; off.
</EM><BR>
<P>I tried the scanner without any other SCSI devices connected and the jumper
<BR>
set. Same result. As you and Ingo said there might be a problem with
<BR>
termination. I will try this out as soon as I get an active terminator for
<BR>
the 50 pin bus.
<BR>
<P><EM>&gt; Doesn't matter, both can be used. You can use the other one to add a
</EM><BR>
<EM>&gt; terminator (about 5-10 Euro).
</EM><BR>
<P>I remembered buying the cable cost me about 80 DM (40 EUR) and I was shocked
<BR>
by the prices for SCSI equipment ever since :)
<BR>
<P><EM>&gt; termination on SCSI adapter). With only one device I never needed a
</EM><BR>
<EM>&gt; terminator with a NCR810 clone.
</EM><BR>
<P>Nope, didn't work either. The cable is roughly 170 cm long, I suppose this
<BR>
should be ok.
<BR>
<P><EM>&gt; Other ideas:
</EM><BR>
<EM>&gt; - I think there are two different SCSI drivers in the Linux kernel for this
</EM><BR>
<EM>&gt; device, did you try both?
</EM><BR>
<P>I will try the other driver tonight and report back to the list.
<BR>
<P>Thank you for your help!
<BR>
