The drivers in the USB 2.0 driver stack ship in Windows XP with SP1 and later versions of the Windows operating system. Windows loads the USB 2.0 driver stack for devices that are attached to eHCI, oHCI, or uHCI controllers. After parsing the information, the hub driver submits the request to the USB host controller extension or further processing. For instance, the hub driver parses a select-configuration request to determine which endpoints will be configured by the request. In addition to hub management, the hub driver also performs preliminary checks and processing of certain requests sent by the USB client driver layer. The hub driver relies on KMDF for power management and PnP functions. Device enumeration and hub management in the new driver are implemented through a set of state machines. Windows loads the hub driver as the FDO in the hub device stack.
