This implements a USB CDC serial port using the Nuvoton USBD driver. The USB handling is based on Nuvoton's BSP sample code, especially the IRQ handlers and descriptor buffer configuration. The descriptors have been adapted to be similar to the AVR version, and RX/TX functions have been written to implement an API closer to LUFA, which is what the SIMM programmer common code needs.
