* Open Host Controller Driver (OHCI)
*
* The USB Open Host Controller driver is a software driver which interfaces
* to the Universal Serial Bus layer (USBA) and the USB Open Host Controller.
* The interface to USB Open Host Controller is defined by the OpenHCI Host
* Controller Interface.
*
* This header file describes the data structures required for the USB Open
* Host Controller Driver to maintain state of USB Open Host Controller, to
* perform different USB transfers and for the bandwidth allocations.

* Root hub information structure
*
* The Root hub is a Universal Serial Bus hub attached directly to the
* Host Controller (HC) and all the internal registers of the root hub
* are exposed to the Host Controller Driver (HCD) which is responsible
* for providing the proper hub-class protocol with the USB driver and
* proper control of the root hub. This structure contains information
* about the root hub and its ports.
