  *  basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers

+ *  On start-up the system will automatically enumerate and function as a 
+ *  USB microphone. By default, the demo will produce a square wave test tone
+ *  when the board button is pressed. If USE_TEST_TONE is not defined in the
+ *  project makefile, incoming audio from the ADC channel 1 will be sampled
+ *  and sent to the host computer instead.
  *
- *  To use, connect a microphone to the ADC channel 1.
+ *  When in microphone mode, connect a microphone to the ADC channel 2.
  *
  *  Under Windows, if a driver request dialogue pops up, select the option
  *  to automatically install the appropriate drivers.
