+ The USB Function Protocol provides an I/O abstraction for a USB Controller
+ operating in Function mode (also commonly referred to as Device, Peripheral,
+ or Target mode) and the mechanisms by which the USB Function can communicate
+ with the USB Host. It is used by other UEFI drivers or applications to
+ perform data transactions and basic USB controller management over a USB
+ Function port.
+
+ This simple protocol only supports USB 2.0 bulk transfers on systems with a
+ single configuration and a single interface. It does not support isochronous
+ or interrupt transfers, alternate interfaces, or USB 3.0 functionality.
+ Future revisions of this protocol may support these or additional features.
