 *
 * Some differences from DIR-885L include a separate USB2 port, separate LEDs
 * for USB2 and USB3, a separate VCC supply for the USB2 slot and no
 * router/extender switch is mounted (there is an empty mount point on the
 * PCB) so this device is a pure router. Also the LAN ports are in the right
