USB at 12Mbps

[jmg85]

Hi,

I understand that V-USB can be used with 12-20MHz microcontrollers in order to run 1.5Mbps USB communication.
I wonder if I can achieve a 12Mbps USB reception with a faster microcontroller. Let’s say 120MHz or so.
Could it be possible?

Many thanks in advance,
Jorge

V-USB has some hand-timed assembly code for each supported speed. Adding a speed requires new code. Also, I wasn't aware of 120MHz AVR microcontrollers.
