Remarks

The client driver for the function host controller registers its EVT_UFX_DEVICE_CONTROLLER_RESET implementation with the USB function class extension (UFX) by calling the UfxDeviceCreate method.

The client driver indicates completion of this event by calling the UfxDeviceEventComplete method.
