Windows loads the xHCI driver as the function device object (FDO) in the device stack for the host controller. The new driver was written by using Kernel Mode Driver Framework (KMDF) interfaces and uses KMDF for all controller power management and PnP events. 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. It also controls the xHCI controller device slots and endpoint contexts. After completing a transfer, the driver handles transfer completion events from the hardware and propagates the events up the driver stack.

The responsibilities of the xHCI driver include initializing MMIO registers and host memory-based data structures for xHCI controller hardware, mapping transfer requests from upper layer drivers to Transfer Request Blocks, and submitting the requests to the hardware. The xHCI driver is the USB 3.0 host controller driver. USB 3.0 host controller driver (Usbxhci.sys) The KMDF driver model reduces complexity and improves stability.
