+ *
+ * Human interface on Xplain-A1:
+ * - RED led close to USB connector is always on after firmware startup
+ * - Led 0 is on when USB line is in IDLE mode, and off in SUSPEND mode
+ * - Led 1 blinks when USB Host have checked and enabled HID Keyboard interface
+ * - The led 2 displays numeric lock status.
+ * - The led 3 displays caps lock status.
+ * - The switch 0 open a note pad and send key sequence "Atmel AVR USB Keyboard"
+ * - All switches can be used to wakeup USB Host in remote wakeup mode.
