USBTXHUBPORTn is an 8-bit read/write register that, like USBTXHUBADDRn, only must be written
when a full- or low-speed Device is connected to transmit 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.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Hub Port
This field specifies the USB hub port number.
