<P>
It looks lie this canner uses the National Semiconductor chip LM9832 which i
<BR>
a complete (almost) USB-scanner in a chip. The internals of the chip looks
<BR>
very much like the LM9830 which is also a scanner on a chip but uses EPP
<BR>
instead of USB. Some minor enhancements are also on the USB version. HP4200
<BR>
uses the LM9830, but in the source for that driver it mentions it is using a
<BR>
USB-EPP bridge, which makes that driver a little far fetched for me. Is there
<BR>
any other scanner that uses the LM9832 chip, or has anyone written any code
<BR>
for an LM9832 based device?
<BR>
<P>I'm asking because the documentation from National does not describe all the
<BR>
details of the communication part, only what the internal registers in the
<BR>
scanner do, which is great, but unfortenatly not enough for me.
<BR>
