NOTICE: Do not attach a USB device or a combination of USB devices that draw a maximum current of more than 500 mA per channel or +5 V. Attaching

devices that exceed this threshold may cause the USB connectors to shut down. See the documentation that accompanied the USB devices for their

maximum current ratings.
