 * Human interface on XMEGA-A3BU Xplained:
 * - XMEGA USART used USARTC0 on J1 connector
 * - Led 0 blinks when USB Host have checked and enabled CDC interface
 * - Led 1 is on when CDC port is open
 * - Green LED close to USB connector is on during data transfer from CDC to UART
 * - Red LED close to USB connector is on during data transfer from UART to CDC
