Porting updates for the UC3B architecture - get UC3B partially enumerating using a modified mouse demo on the EVK1101. Implement a software FIFO for the endpoint banks; datasheet hints that this can be done through hardware as on the AVR8 architecture, but the correct method to do this not discovered yet.
