<EM>&gt; Hello,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I'm wondering if anyone has achieved success using SANE with the
</EM><BR>
<EM>&gt; Microtek ScanMaker X6 USB? If so, using what hardware and what Linux
</EM><BR>
<EM>&gt; kernel?
</EM><BR>
<P>Having written half the driver I do ;-)
<BR>
<P>It worked with test5. It _fails_ for me in test8.
<BR>
I discovered that today and I'll look into the cause.
<BR>
<P><EM>&gt; Currently, I'm able to get the driver to see the scanner, and to get
</EM><BR>
<EM>&gt; scanimage and xscanimage to see the scanner and query its capabilities.
</EM><BR>
<EM>&gt; However, if I try to actually acquire an image or do a 'scanimage -T',
</EM><BR>
<EM>&gt; the entire machine locks up (the results are attached if anyone cares to
</EM><BR>
<EM>&gt; see them).
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; This is on an i386 architecture (actually an Athlon/VIA chipset) using
</EM><BR>
<EM>&gt; the UHCI USB driver, Linux kernel 2.4.0-test8. For testing, I ran in the
</EM><BR>
<EM>&gt; console, with all nonessential modules (network, sound, etc.) unloaded.
</EM><BR>
<EM>&gt; Also, I built SANE using 'configure --enable-scsibuffersize=32768' as
</EM><BR>
<EM>&gt; this appears to be necessary to get the driver to work at all.
</EM><BR>
<P>SANE allows you to limited the buffersize dynamically
<BR>
via enviroment variables. I consider this a deficiency in
<BR>
SANE. It should accept a smaller buffer returned by the OS.
<BR>
<P>Could you please run your oops through ksymoops ?
<BR>
<P><P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Regards
<BR>
