</EM><BR>
<EM>&gt; I read a message (posted by Joerg Budweg posted Sun Jan 09 2000) in the
</EM><BR>
<EM>&gt; January mailist archive explaining how to change mustek.desc and
</EM><BR>
<EM>&gt; mustek.c in order to make the backend work with the &quot;Plus&quot;. I've added a
</EM><BR>
<EM>&gt; new line in mustek.desc:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; :model &quot;SCANNER V101&quot;
</EM><BR>
<EM>&gt; :comment &quot;1 pass; (f/w == 1.01; scsi id XC06 S1212IDW)&quot;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; (I couldn't get the scsi id from the command 'SANE_MUSTEK_DEBUG=3;
</EM><BR>
<EM>&gt; scanimage -h -d mustek &gt; /dev/null', as suggested, because I don't have
</EM><BR>
<EM>&gt; the debug info displayed)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; then changed line 765 in mustek.c into:
</EM><BR>
<EM>&gt; else if (strncmp(model_name, &quot;XC06&quot;, 4) == 0)
</EM><BR>
<EM>&gt; ^
</EM><BR>
<EM>&gt; Now the scanner works fine. Next step will be to try to change sg.c to
</EM><BR>
<EM>&gt; increase buffer size.
</EM><BR>
<P>I would recommend to install a recent version of the SG driver (2.1.36
<BR>
for example) from http::/www.torque.net/sg. It supports the change of
<BR>
the buffer size at program run time; if you use one of the last CVS
<BR>
snapshots of Sane, you can select the buffer size by setting the
<BR>
environment variable SANE_SG_BUFFERSIZE to the desired buffer size (in
<BR>
bytes). But beware: If your try to use &quot;really large&quot; buffers (roughly
<BR>
more than 1 MB), it can happen that the kernel cannot allocate this
<BR>
buffer. And if my memory is right, the Mustek backend restricts the
<BR>
buffer size to 64 kB for some scanners. But don't ask any details, for
<BR>
which scanner and why...
