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