<P><EM>&gt; I have posted a lot re: this scanner. I had it working under
</EM><BR>
<EM>&gt; sane1.0.1. Had to format hard drive, and now trying to get it
</EM><BR>
<EM>&gt; working with latest SNAPSCAN backed, and sane 1.0.4.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The scanner will generally start scanning, but can never make it
</EM><BR>
<EM>&gt; through an entire scan. The sound (of it working) usally comes to a
</EM><BR>
<EM>&gt; halt, following by a lengthy pause, and then I get an error message
</EM><BR>
<EM>&gt; saying that there was a failure with devie i/o.
</EM><BR>
<P>There are a few lines in snapscan-source.c in the new snapscan which
<BR>
look like this:
<BR>
<P>if(ps-&gt;pss-&gt;pdev-&gt;model == ACER300F
<BR>
&nbsp;&nbsp;&nbsp;||
<BR>
&nbsp;&nbsp;&nbsp;ps-&gt;pss-&gt;pdev-&gt;model == SNAPSCAN310
<BR>
&nbsp;&nbsp;&nbsp;||
<BR>
&nbsp;&nbsp;&nbsp;ps-&gt;pss-&gt;pdev-&gt;model == SNAPSCAN1236S
<BR>
&nbsp;&nbsp;&nbsp;||
<BR>
&nbsp;&nbsp;&nbsp;ps-&gt;pss-&gt;pdev-&gt;model == VUEGO310S
<BR>
&nbsp;&nbsp;&nbsp;||
<BR>
&nbsp;&nbsp;&nbsp;ps-&gt;pss-&gt;pdev-&gt;model == VUEGO610S)
<BR>
&nbsp;&nbsp;{
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;ps-&gt;pss-&gt;expected_read_bytes = (size_t) ps-&gt;absolute_max;
<BR>
&nbsp;&nbsp;}
<BR>
<P>Could you try to add your model in the if test (or just put your model
<BR>
instead of another one). Then recompile. It corrected a problem rather
<BR>
similar for other models.
<BR>
<P>If this is not enough, there are a few other places in snapscan code
<BR>
with the same kind of test. You may try to do the same modification
<BR>
there too.
<BR>
<P><PRE>
