<EM>&gt; &gt;%_I tried scanimage -d /dev/scanner and got a similar response:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; scanimage: open of device /dev/scanner failed: Invalid argument
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The logfile looks more interesting - 'access to resource has been
</EM><BR>
<EM>&gt; denied'. It's attached.

<P><P>Sorry, I haden't seen your debug output.
<BR>
<P>You should verify your /dev/scanner link. ( &quot;ls -l /dev/scanner&quot; )
<BR>
Can you get scanimage working as root ? ( if so, check users read-write
<BR>
permissions )
