<EM>&gt; Anyone know what is going on? How do I turn on the debug info for the
</EM><BR>
<EM>&gt; snapscan backend?
</EM><BR>
<P>export SANE_DEBUG_SNAPSCAN=128
<BR>
<P>(or some other number)
<BR>
<P><EM>&gt; (I might play around with the code a bit). Finally, does this error
</EM><BR>
<EM>&gt; message below mean that the backend sent a message to the scanner, but
</EM><BR>
<EM>&gt; the scanner didn't identify itself, and hence the backend thought that
</EM><BR>
<EM>&gt; nothing was connected there?
</EM><BR>
<EM>&gt; ----
</EM><BR>
<EM>&gt; [root@zootv /usr/src/sane-1.0.2]# scanimage -d snapscan:/dev/scanner
</EM><BR>
<EM>&gt; scanimage: open of device snapscan:/dev/scanner failed: Invalid argument
</EM><BR>
<P>Probably you don't have a device file or symlink /dev/scanner. Try
<BR>
&quot;scanimage -d snapscan:/dev/sga&quot;, or make the symlink /dev/scanner
<BR>
pointing to /dev/sga.
