Detailed Description

The EFI_USB_IO_PROTOCOL provides four basic transfers types described in the USB 1.1 Specification.

These include control transfer, interrupt transfer, bulk transfer and isochronous transfer. The EFI_USB_IO_PROTOCOL also provides some basic USB device/controller management and configuration interfaces. A USB device driver uses the services of this protocol to manage USB devices.
