USB requires a crystal. Internal clock is not accurate enough. So USB communication but no crystal won't do. > BTW, I wonder how Jal deals with clock speed runtime modification... I don't think it does at all. Everything that has some timing in it (like delay, serial...) only works correct at the specified clock speed. If you've specified 4MHz clock, but run at 32kHz, a _usec_delay(1000) won't delay 1 ms, but 125ms.
