1/** @file 2 Defines the PEI_USB_IO_PPI that the USB-related PEIM can use for I/O operations 3 on the USB BUS. This interface enables recovery from a 4 USB-class storage device, such as USB CD/DVD, USB hard drive, or USB FLASH 5 drive. These interfaces are modeled on the UEFI 2.3 specification EFI_USB_IO_PROTOCOL. 6 Refer to section 16.2.4 of the UEFI 2.3 Specification for more information on 7 these interfaces. 8 9Copyright (c) 2006 - 2013, Intel Corporation.
