ReactOS currently ships with drivers for USB 1.x (OHCI/UHCI) and USB 2.x (EHCI) controllers only. More and more modern computers come with USB 3.x controllers (XHCI), so ReactOS should come with a driver for them rather sooner than later. This is a side project that can be implemented independently. In order to support all the enhanced features afforded by USB3 specifications, a new generation of host controller is required. The implementation of this host controller standard is described in hardware by XHCI (Extensive host controller interface) which is quite complex and different from previous generations with its difficult terminology and modeling.
