The BMC includes a path switching circuit, a host interface circuit, a universal serial bus (USB) hub controller, a USB physical layer circuit, and a control circuit. The host interface circuit is adapted to be electrically connected to a host circuit outside the BMC. The USB physical layer circuit is adapted to be electrically connected to an external USB host or an external USB device outside the BMC. The control circuit controls the path switching circuit to selectively couple the host interface circuit to the USB hub controller, selectively couple the USB hub controller to the USB physical layer circuit, or selectively couple the host interface circuit to the USB physical layer circuit.
