<EM>&gt; Please forgive me if this information was already known. I spent a

<EM>&gt; lot of time searching archives in various places looking for someone
</EM><BR>
<EM>&gt; who had successfully got a Microtek ScanMaker E3 Plus with parallel
</EM><BR>
<EM>&gt; port working under Linux and came up with many dead ends. Lots of
</EM><BR>
<EM>&gt; folks had got to the point of trying the following:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; % scanimage -d microtek2:/dev/sg0 &gt; test
</EM><BR>
<EM>&gt; scanimage: open of device microtek2:/dev/sg0 failed: Error during
</EM><BR>
<EM>&gt; device I/O
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; If there was a solution posted, I never saw it. I'm writing this email
</EM><BR>
<EM>&gt; as a public service for those who may still be trying and hoping but
</EM><BR>
<EM>&gt; haven't seen anything.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Step 1: Get your scanner working/visible as a SCSI device under
</EM><BR>
<EM>&gt; Linux.
</EM><BR>
<P>This is also written in the Sane-Faq:

<A HREF="http://www.xs4all.nl/~ljm/SANE-faq.html">http://www.xs4all.nl/~ljm/SANE-faq.html</A>
<BR>
I guess you didn't find it?
<BR>
<P><EM>&gt; Step 2: Get your scanner working/visible with sane
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; This is the part I was stuck at. It turns out that the problem was
</EM><BR>
<EM>&gt; that my version of the microtek2 backend was not recognizing the model
</EM><BR>
<EM>&gt; as belonging to an E3 plus. I hacked the code to recognize my model
</EM><BR>
<EM>&gt; (0x90) as the model listed as an E3Plus (0x92.) I've been happily
</EM><BR>
<EM>&gt; scanning since.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The microtek2 backend I used was microtek2-pre0.9.020100.tar.gz as
</EM><BR>
<EM>&gt; found at <A HREF="ftp://ftp.muc.de/people/bernds/mtek2/">ftp://ftp.muc.de/people/bernds/mtek2/</A> I don't know if this
</EM><BR>
<EM>&gt; was necessary, but it's the one I used. Then I patched the code as
</EM><BR>
<EM>&gt; follows:
</EM><BR>
<P>The current version is 0.9 or 0.10.
<BR>
It's available at <A HREF="http://home.t-online.de/home/karsten.festag">http://home.t-online.de/home/karsten.festag</A>
<BR>
Maybe this one needs to change too.
<BR>
It's a good thing you got it going.
<BR>
If I remember correctly, some time ago someone used also a scanner with
<BR>
modelcode 90, but after patching the backend, it still didn't work.
<BR>
Maybe that's the reason it was left out of the backend. Because there
<BR>
were other issues with this backend.
<BR>
<P><EM>&gt; + case 0x90:
</EM><BR>
<EM>&gt; + mi-&gt;model_code = 0x92;
</EM><BR>
<EM>&gt; + *model_string = &quot;E3+ / Vobis HighScan&quot;;
</EM><BR>
<EM>&gt; + break;
</EM><BR>
<P>I'm no programmer, so maybe this is a stupid question, but the line:
<BR>
<EM>&gt; + mi-&gt;model_code = 0x92;
</EM><BR>
What does it do?
<BR>
In the source file this line is not set at the other models. Could it be
<BR>
that this makes a difference in functionality?
