USBRXHUBPORTn is an 8-bit read/write register that, like USBRXHUBADDRn, only must be
written when a full- or low-speed Device is connected to receive endpoint EPn via a USB 2.0 hub.
This register records the port of the USB 2.0 hub through which the target associated with the
endpoint is accessed.
Note: USBTXHUBPORT0 is used for both receive and transmit for endpoint 0.

compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
