I'm a somewhat devoted Avr hack, however, the Arm's are sucking up my interest due to usb capabilities. arm-gcc is proving to be a real bear, however (.S files, .ld's, oh my!). So, has anyone played with the usb Avr flavor? How about demo boards and/or working examples? I've been fairly happy with the si-labs cp2102 usb<->uart with the avr, but it's not always a perfect of very flexible solution...
