The secondary USB controller on the rb3gen2 is routed directly to a
mico-USB port where it can be used for EUD debugging or in OTG mode.
Configure the controller to prefer peripheral mode (as this is almost
always more useful) and describe the connector, vbus supply, and ID pin.
OTG/Host mode is untested as I don't have micro-USB OTG cables to hand.
