An interfacing device is disclosed which is comprised of a read-only memory (ROM) device, a power regulator, a plurality of specific ports, a link layer controller, a physical layer arbiter, a switching unit which switches the state of the power provided to the peripheral equipment through specific ports, a resetting unit which resets the link layer controller, an indicating unit which displays the state of the power provided to the physical layer arbiter and the operation state of the physical layer arbiter. The present invention prevents the interfacing device and other peripheral equipment from being damaged due to the reverse current generated from specific peripheral equipment, and provides for a reset of the interfacing device, and thus restarting the computer system is not needed in order to reset the interfacing device.
