<P><EM>&gt; Hi,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; have you modified your snapscan.conf? It should look like

<EM>&gt; scsi Color

<EM>&gt; /dev/usbscanner

<EM>&gt; If this doesn't change the behaviour, set SANE_SNAPSCAN_DEBUG=255, run

<EM>&gt; scanimage -L again and mail me the output.

I recompiled sane using the cvs files from the sourceforge page.
<BR>
I changed my snapscan.conf, and my dll.conf so that it only tries to load the snapscan backend. Now when I run scanimage -L it does not freeze for so long, then it puts up the no scanner found message. (I am guessing the freeze time,is time that sane is trying different drivers.)
<BR>
<P>I am not sure how to set SANE_SNAPSCAN_DEBUG=255? Should I enter this line in the make file, pass the line as an arguement to ./configure? I ran the following command 'grep -l SANE_SNAPSCAN_DEBUG=255 *' in the sane-backend dir, the backend dir, and the frontend dir but came up with nothing.
<BR>
<P>I tried just setting SANE_SNAPSCAN_DEBUG=255 in my shell window, and then running scanimage -L, but the output was the same as it always is.
<BR>
<P>Let me know how to set SANE_SNAPSCAN_DEBUG=255 and I will try again, and email you the output.
<BR>
<P>&lt;output&gt;
<BR>
storm:/usr/local/etc/sane.d# scanimage -L
<BR>
<P>No scanners were identified. If you were expecting something different,
<BR>
check that the scanner is plugged in, turned on and detected by the
<BR>
find-scanner tool (if appropriate). Please read the documentation which came
<BR>
with this software (README, FAQ, manpages).
<BR>
&lt;/output&gt;
<BR>
<P>Thanks for your help
