USB resistance set. (This ball should be left unconnected.)
USB_VBUS
I/O 5V USB VBUS. USB_VBUS is an output only in peripheral mode during SRP
F
signaling. Host mode requires that an external voltage source of 5 V at 8 mA
or more (per the OTG specification) be applied to VBUS. The voltage source
needs to be able to charge and discharge VBUS, thus an ON/OFF switch is
required to control the voltage source. A GPIO can be used for this purpose
(This ball should be pulled low when USB is unused or not present.)
