I am not sure what happened, but I ran scanimage -L with in the debug mode. The scanner was recognized?????? All is well that ends well. The only thing that may have been different was that I mounted the usbdevfs before running scanimage. I have been fooling with this stuff for so long now, who knows what I did diff this time around. Anyway, I really appreciate the effort you went to to help me out. The debug mode may help me help myself out if I encounter this prob again. Hopefully things keep working.

<P><EM>&gt; Hi,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; I am not sure how to set SANE_SNAPSCAN_DEBUG=255? Should I enter this line
</EM><BR>
<EM>&gt; &gt; in the make file, pass the line as an arguement to ./configure? I ran the
</EM><BR>
<EM>&gt; &gt; following command 'grep -l SANE_SNAPSCAN_DEBUG=255 *' in the sane-backend
</EM><BR>
<EM>&gt; &gt; dir, the backend dir, and the frontend dir but came up with nothing.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Actually it's SANE_DEBUG_SNAPSCAN ... just execute
</EM><BR>
<EM>&gt; &quot;export SANE_DEBUG_SNAPSCAN=255&quot; in your shell before running scanimage.
