The app note actualy says "max throughput aprox 80 Kb/s", which
might not be what the USB bus is capable of. *BUT*, since this
app note (and the "RS-232 Emulation Firmware") are ment to
be a replacement for a former serial line solution, I don't
se that as a major problem with *this* app note (and related
firmware). And lower speed does not automaticly meen lower quality.

Now, with that said, I have just found what I think is the
software (firmware) that the app note talks about. Download
is about to begin (only dial-up available here :-) )...
