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. + + Copyright (c) 2015 - 2017, Intel Corporation.
