<EM>&gt; The main thing I want to work on is getting USB support integrated
</EM><BR>
<EM>&gt;fully into the scanscan driver so that its a config file option
</EM><BR>
<EM>&gt;instead of a compile time option. I'll also be happy to test
</EM><BR>
<EM>&gt;anything others develop to make sure it works with a 640BU.
</EM><BR>
<P>Yes, I'd like that too. It seems strange that USB is mutually
<BR>
exclusive at compile-time with SCSI.
<BR>
<P>My Agfa Snapscan 1212U mostly works now. I only get the occasional
<BR>
permanent lock-up of SANE and the scanner now. It scans at all tested
<BR>
resolutions in colour, though I haven't tried gey-scale yet or any of
<BR>
the other fancy options. It *really* did not like it when I tried to
<BR>
scan at 300 dpi and forgot to remove the &quot;preview&quot; option from the
<BR>
command-line.
<BR>
<P>I'd still like to find the conditions under which it locks up, and
<BR>
find a way of resetting it without rebooting.
<BR>
<P><EM>&gt; Oh yeah, and if SANE tries to ever scan the system to see whats out
</EM><BR>
<EM>&gt; their and access /dev/scanner then it actually passes a USB bulk_msg
</EM><BR>
<EM>&gt; call which locks up the kernel scanner.o driver and then SANE and
</EM><BR>
<EM>&gt; makes them both unusable.
</EM><BR>
<P>Ah, maybe that's the cause of the lockup. What is a USB bulk_msg? Do
<BR>
you know why it locks up the kernel driver? &quot;scanimage -T&quot; seems to
<BR>
work OK most of the time, it's only when a previous operation failed
<BR>
that it locks up.
