- CDC Output seems to be working
- USB Keyboard output has not been tested, but is "ready"
- UART and Timers have not been tested, or fully utilized
- Issues using Timer 0
- Initial template for MBC-55X Scan module (only module currently compatible with the arm build)
- Updated the interface to the AVR usb module for symmetry with the ARM usb module
- Much gutting was done to the Teensy 3 usb keyboard module, though not in an ideal state yet

- Full support (NKRO, provided the USB module can handle it)
- Full LED support (available to the macro modules per input signals)
- Reset/Hold line support
- Handles repeat rate issues (keyboard does not send key updates as most
  keyboards do...)
