HI,
<BR>
<P>As i knew, Avision, Silitek(HP OEMs), Primax , most use
<BR>
genesys logic's usb chip and some scanlogic.
<BR>
<P>My Visioneer 8600 usb SANE, have code about genesys logic
<BR>
about CONTROL modification on scanner.c
<BR>
<P>please visit <A HREF="http://www.littlecms.com/iphoto/otlinux.htm">http://www.littlecms.com/iphoto/otlinux.htm</A>
<BR>
And maybe have a discussion about merge ioctl part.
<BR>
<P>kw
<BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt;are you sure that the scanner is indeed controlled with CONTROL and _not_
</EM><BR>
BULK
<BR>
<EM>&gt; &gt;urbs ?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Yes.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt;If so, the existing kernel drivers will not work.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; That's not a big problem. I coded the ioctl_scanner() function of the
</EM><BR>
<EM>&gt; USB stack `scanner.c' file in 2.3.x and 2.4.x linux kernels, to be used
</EM><BR>
<EM>&gt; by the hp4200 scanner backend; and a modified version could work for
</EM><BR>
<EM>&gt; those scanners.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt;To me this protocol is absolutly alien.
</EM><BR>
<EM>&gt; &gt;It has _no_ connection to the protocol of the 5300.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; That's really a pity. I thought those 8-byte vectors could be a kind
</EM><BR>
<EM>&gt; of a ``SCSI scanner'' like command. Anyway, rev-eng is fun (I hope).
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; HTH
</EM><BR>
<EM>&gt; &gt; Oliver
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Thank you!
