<EM>> > Step 1: Get your scanner working/visible as a SCSI device under

<EM>> > Linux.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> This is also written in the Sane-Faq:
|
|
</EM><BR>
|
|
<EM>> <A HREF="http://www.xs4all.nl/~ljm/SANE-faq.html">http://www.xs4all.nl/~ljm/SANE-faq.html</A>
|
|
</EM><BR>
|
|
<EM>> I guess you didn't find it?
|
|
</EM><BR>
|
|
<P>Actually, I did find various pieces I posted in various places. I
|
|
<BR>
|
|
simply wanted to put it all in one document specifically for the
|
|
<BR>
|
|
E3Plus. (I forget where all I searched but I went through a few
|
|
<BR>
|
|
different mailing lists including this one and never found evidence
|
|
<BR>
|
|
that someone had success.) My own research took me to the
|
|
<BR>
|
|
scsi-over-parallel patch pretty quickly, but it was a little ambiguous
|
|
<BR>
|
|
as to which the most recent one was - hence my inclusion of the
|
|
<BR>
|
|
information.
|
|
<BR>
|
|
<P><EM>> If I remember correctly, some time ago someone used also a scanner with
|
|
</EM><BR>
|
|
<EM>> modelcode 90, but after patching the backend, it still didn't work.
|
|
</EM><BR>
|
|
<EM>> Maybe that's the reason it was left out of the backend. Because there
|
|
</EM><BR>
|
|
<EM>> were other issues with this backend.
|
|
</EM><BR>
|
|
<P>Not sure. My assumption was that they had already coded the
|
|
<BR>
|
|
instructions for the E3+ and I knew mine was an E3+ - hence it seemed
|
|
<BR>
|
|
safe to kludge mine to being recognized as model code 92. I would
|
|
<BR>
|
|
also guess that this is not necessarily safe in the general case as
|
|
<BR>
|
|
perhaps there are other model code 90 Microtek2 scanners that are not
|
|
<BR>
|
|
E3+.
|
|
<BR>
|
|
<P><P><EM>> > + case 0x90:
|
|
</EM><BR>
|
|
<EM>> > + mi->model_code = 0x92;
|
|
</EM><BR>
|
|
<EM>> > + *model_string = "E3+ / Vobis HighScan";
|
|
</EM><BR>
|
|
<EM>> > + break;
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> I'm no programmer, so maybe this is a stupid question, but the line:
|
|
</EM><BR>
|
|
<EM>> > + mi->model_code = 0x92;
|
|
</EM><BR>
|
|
<EM>> What does it do?
|
|
</EM><BR>
|
|
<P>As above - I said, "since you think this is model code 0x90 (the case
|
|
<BR>
|
|
statement) then pretend it's really model code 0x92 (the line you
|
|
<BR>
|
|
asked about) and set the model_string ..." Hence the code continued
|
|
<BR>
|
|
on thinking it had really found model code 0x92 - which the code was
|
|
<BR>
|
|
commented as thinking was an E3+.
|
|
<BR>
|
|
<P><EM>> In the source file this line is not set at the other models. Could it be
|
|
</EM><BR>
|
|
<EM>> that this makes a difference in functionality?
|
|
</EM><BR>
|
|
<P>I'm not sure I understand your question. If you mean "Was there
|
|
<BR>
|
|
anything assigned to model code 0x90?" the answer was No. That value
|
|
<BR>
|
|
was not recognized - hence the I/O error reported by the backend. (It
|
|
<BR>
|
|
didn't know how to talk to any scanner listed.)
|
|
<BR>
|
|
<P>Hope that helps,
|
|
