Hi,
<BR>
<P><EM>&gt; I've got sane-1.0.3 and linux-2.4.0-test9-pre6. I've tried hand
</EM><BR>
<EM>&gt; crafting the USB patches to work with sane-1.0.3, but it fails to
</EM><BR>
<EM>&gt; recognise my scanner's existence even after I got the patches to
</EM><BR>
<EM>&gt; apply. (The same thing happens under kernel 2.2.15 with USB backport)
</EM><BR>
<P>With sane-1.0.3 it should be quite simple. You get the USB files (from
<BR>
<A HREF="http://www.ginko.de/user/oschwartz/snapscan/snapscan-usb.tgz">http://www.ginko.de/user/oschwartz/snapscan/snapscan-usb.tgz</A>), remove the
<BR>
comments for USB includes from snapscan.c and snapscan.h and recompile.
<BR>
<P><EM>&gt; I've followed all the documentation I could find on the 1212U, it
</EM><BR>
<EM>&gt; seems to be the older one that doesn't use firmware upload. How do I
</EM><BR>
<EM>&gt; debug the problem? I've tried 'export SANE_DEBUG_SNAPSCAN=255', but
</EM><BR>
<EM>&gt; all it tells me is
</EM><BR>
<P><EM>&gt; [snapscan] add_device: error opening device /dev/usb/scanner0:
</EM><BR>
<EM>&gt; Invalid argument
</EM><BR>
<P>That looks like an easy one... Does the device (/dev/usb/scanner0) exist? At
<BR>
least on my machine (2.2.16 with USB backport) the correct device is
<BR>
/dev/usbscanner. You have to supply the devicename in snapscan.conf, e.g.
<BR>
<P>scsi AGFA
<BR>
scsi COLOR
<BR>
scsi Color
<BR>
/dev/usbscanner
<BR>
<P>Good luck,
<BR>
<P>Oliver
