NUMBER	BIT NAME	DESCRIPTION
7:0	PRTR3	Port remap register for port 3.
		When a hub is enumerated by a USB Host Controller, the hub is only
		permitted to report how many ports it has; the hub is not permitted to select
		a numerical range or assignment. The Host Controller will number the
		downstream ports of the hub starting with the number '1', up to the number
		of ports that the hub reported having.
		The host's port number is referred to as "Logical Port Number" and the
		physical port on the hub is the “Physical Port Number". When remapping
		mode is enabled (see PRTMAP_EN in Register 08h: Configuration Data
		Byte 3) the hub's downstream port numbers can be remapped to different
		logical port numbers (assigned by the host).
		Note: The OEM must ensure that Contiguous Logical Port Numbers are
		used, starting from #1 up to the maximum number of enabled ports;
		this ensures that the hub's ports are numbered in accordance with
		the way a Host will communicate with the ports.
