/** @file\r
  Defines the PEI_USB_IO_PPI that the USB-related PEIM can use for I/O operations\r
  on the USB BUS.  This interface enables recovery from a\r
  USB-class storage device, such as USB CD/DVD, USB hard drive, or USB FLASH\r
  drive.  These interfaces are modeled on the UEFI 2.3 specification EFI_USB_IO_PROTOCOL.\r
  Refer to section 16.2.4 of the UEFI 2.3 Specification for more information on\r
  these interfaces.\r
