     * The LinkSprite pcDuino2 board is almost identical to the older
     * LinkSprite pcDuino1 board. The only software visible difference
     * is that the pcDuino2 board got a USB VBUS voltage regulator, which
     * is controlled by the PD2 pin (pulled-up by default). Also one of
     * the USB host ports has been replaced with a USB WIFI chip.
