Hi Ken,

I took a stab at this a year ago for the AT91RM9200.  I never did get it
working.  As I recall, the main issue was that the AT91 UDP takes care
of some low-level protocol in hardware, while the existing usbdcore code
does this in software.

Unfortunately, I got pulled away from this work and never did manage to
get back to it.  I would be happy to send you what I have if you are
interested.

Also, in case you missed it, Joey Oravec has managed to get USB serial
working on the AT91SAM9261 using sample Atmel code (see
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30079).  Joey
was kind enough to send me his code and I am in the process of porting
it to the AT91RM9200, when I can fit in the time.

Regards,
../fam
