The switching device includes a universal serial bus (USB) connector, a multiplexer, a USB hub and a controller. The USB connector is connected to a USB device or a voice control device. The multiplexer is electrically connected to the USB connector. The USB hub is electrically connected to the multiplexer and used to output a USB detection signal. The controller is electrically connected to the multiplexer and the USB hub, and used to output a reminder command.
