Hi all,
<BR>
<P>I just wanted to update you all on the status of Linux USB since I get
<BR>
(and answer) most of the USB scanner related questions that cross the
<BR>
linux-usb list.
<BR>
<P>I've just released version 0.3.4 of my driver. Hopefully it'll find
<BR>
itself in the Linux kernel version 2.3.41 (or shortly thereafter). The
<BR>
type of questions I generally get are 'Is Scanner XXX supported?'. To
<BR>
which I generally reply that yes it's supported by the driver. However,
<BR>
the driver is only providing the communications. If it isnt' supported, I
<BR>
ask for some info so that I can put it into the driver. It's apps (or
<BR>
backends in SANE's case) that need to do the work.
<BR>
<P>At this time, most USB HP scanners are working with the SANE HP backend
<BR>
w/o any modifications. The HP6300C requires that HP backend version 0.83
<BR>
be installed/compiled (if I remember correctly). While I've been reading
<BR>
that most manufactures aren't very cooperative in giving specs out, I
<BR>
don't think it hurts to experiment a little by commnunicating with USB
<BR>
scanners using known command strings. USB communications are generally
<BR>
very easy (or course I'm only basing this on my experience with the HP
<BR>
scanners). Read the scanner.txt and scanner-hp-sane.txt Documentation
<BR>
from the latest dev kernels to see how easy it is. I'm in contact with a
<BR>
fellow that is doing some prelim stuff in perl in order to communicate
<BR>
across USB using the scanner driver (ins't perl just great! ;). I'm
<BR>
hoping that some of the developers or future developeres or want-to-be
<BR>
developers will at least experiment now that this is available.
<BR>
<P>Thanks,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/\/elson
