Detailed Description

The EFI_USB2_HC_PROTOCOL provides USB host controller management, basic data transactions over a USB bus, and USB root hub access.

A device driver that wishes to manage a USB bus in a system retrieves the EFI_USB2_HC_PROTOCOL instance that is associated with the USB bus to be managed. A device handle for a USB host controller will minimally contain an EFI_DEVICE_PATH_PROTOCOL instance, and an EFI_USB2_HC_PROTOCOL instance.
