Abstract: A multi-function network card comprises a universal serial bus (USB) interface. A HUB or control circuit is coupled to the USB interface, the HUB or control circuit includes pluralities of ports formed thereon for connecting computer periphery device. A function control circuits is connected to the ports for driving the computer periphery device and pluralities of media attached units respectively are connected to the function control circuit for connecting the computer periphery device. Pluralities of sensor are respectively coupled to the function control circuit or the pluralities of media attached units, wherein the pluralities of sensor may detect whether the computer periphery device is connected or not; and a power control means is connected to the USB interface by a first terminal and connected to the function control circuit by a second terminal.
