Windows: WinUSB: Guard against erroneous reporting of devices During enumeration, obtaining the port number via SPDRP_ADDRESS might return a bogus value for some third-party HCD drivers. If this occurs, we might end up reporting the device as having the VID/PID from the last successful enumeration. Guard against this particular situation by clearing the USB_NODE_CONNECTION_INFORMATION_EX structure before issuing the DeviceIoControl() call.
