+ *\r
+ * Audio demonstration application. This gives a simple reference\r
+ * application for implementing a USB Audio Output device using the\r
+ * basic USB Audio drivers in all modern OSes (i.e. no special drivers\r
+ * required).\r
+ * \r
+ * On start-up the system will automatically enumerate and function\r
+ * as a USB speaker. Incoming audio will output in 8-bit PWM onto\r
+ * the timer output (timer 3 for the AT90USBXXX6/7 USB AVRs, timer 1 for\r
+ * the AT90USBXXX2 controller AVRs) compare channel A for AUDIO_OUT_MONO\r
+ * mode, on channels A and B for AUDIO_OUT_STEREO and on the board LEDs\r
+ * for AUDIO_OUT_LEDS mode. Decouple audio outputs with a capacitor and\r
+ * attach to a speaker to hear the audio.\r
+ * \r
+ * Under Windows, if a driver request dialogue pops up, select the option\r
+ * to automatically install the appropriate drivers.\r
