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.
