+ *  USB to Serial bridge project. This project allows a USB AVR to serve

+ *  virtual COM port.
+ *
+ *  The AVR's hardware USART's settings will change to mirror as closely as
+ *  possible the serial settings set on the host. However, due to hardware
+ *  limitations, some options may not be supported (baud rates with unacceptable
+ *  error rates at the AVR's clock speed, data lengths other than 6, 7 or 8 bits,
+ *  1.5 stop bits, parity other than none, even or odd).
  *  
  *  After running this demo for the first time on a new computer,
  *  you will need to supply the .INF file located in this demo
