It also controls the xHCI controller device slots and endpoint contexts.

The xHCI driver is new in Windows 8 and is not an extension of the eHCI miniport driver that was available in earlier versions of the operating system. The new driver is extensible and is designed to support other types of host controller drivers that are expected to be developed in the future. The USB host controller extension serves as a common abstracted interface to the hub driver, provides a generic mechanism for queuing requests to the host controller driver, and overrides certain selected functions.

The xHCI driver, when ready for processing, retrieves the request from the queue. The responsibilities of the USB host controller extension driver are:. The new hub driver, in the USB driver stack for 3. The hub driver primarily performs these tasks:. Windows loads the hub driver as the FDO in the hub device stack.

Device enumeration and hub management in the new driver are implemented through a set of state machines. In addition to hub management, the hub driver also performs preliminary checks and processing of certain requests sent by the USB client driver layer.

For instance, the hub driver parses a select-configuration request to determine which endpoints will be configured by the request.

After parsing the information, the hub driver submits the request to the USB host controller extension or further processing. The drivers in the USB 2.

The Usbuhci. The Usbohci. The Usbehci. In all versions of Windows that support USB 2. Whenever the operating system detects that both types of controller are present, it creates two separate device nodes, one for each host controller.

Windows subsequently loads the Usbehci.
