<EM>&gt; &gt; &gt; I recently upgraded to Slackware 8.0 My old version of scanmimage
</EM><BR>
<EM>&gt; &gt; &gt; woldn't work. Kept getting segmentation Errors. So I loaded
</EM><BR>
<EM>&gt; &gt; &gt; version 1.0.5, compiled, installed, visited /usr/local/sane.d
</EM><BR>
<EM>&gt; &gt; &gt; etc. and so on.
</EM><BR>
<EM>&gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt; Now when I put in a command
</EM><BR>
<EM>&gt; &gt; &gt; scanimage -depson:/dev/usb/scanner0
</EM><BR>
<EM>&gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt; the light comes on (I am making contact at least) but the scanner
</EM><BR>
<EM>&gt; &gt; &gt; does not move. If I switch the scanner off I get an i-o error
</EM><BR>
<EM>&gt; &gt; &gt; message. Ctrl-C does not interrupt the program.
</EM><BR>
<EM>&gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt; Scanner works under Win98 but the software over there is pretty
</EM><BR>
<EM>&gt; &gt; &gt; restrictive. Any thoughts?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Nothing in the hardware has changed. I have an Epson 1240U connected
</EM><BR>
<EM>&gt; via my usb port. Under Slackware 7.1 it used to work.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The kernel has usb software built in. And as I noted above I can make
</EM><BR>
<EM>&gt; contact with the scanner. I just can't get it to scan.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Here is a snippet from dmesg:
</EM><BR>
<EM>&gt;
</EM><BR>

</EM><BR>
<EM>&gt; at present.)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<P>I have an Epson 1240U and upgraded to Slackware 8.0 last week, but
<BR>
everything works fine for me, just as it did under Slackware 7.1 (I run
<BR>
sane 1.04). Try to recompile sane 1.04 and see if it works ?
<BR>
<P>Note that the libs under 8.0 have changed significantly, which may
<BR>
explain the segfaults.
