Various connector types are used are used to connect a personal computer to another devices.  These connectors include an Ethernet connector, an IEEE 1394 connector, a parallel connector, a serial connector, IBM Personal System 2 (PS/2) connector, a Video Graphics Array (VGA) connector, a Digital Visual Interface (DVI) connector, a Small Computer System Interface (SCSI) connector, a Tip Ring Sleeve (TRS) connector, and a Universal Serial Bus (USB) connector.  The devices that these connectors connect to a personal computer include a keyboard, a printer, a disk drive, a portable media player, and a digital camera. 
The socket on a personal computer to which a connector may be connected is commonly referred to as a port. 
A port on a computer is a known vulnerability due to the extrication of data from the computer or the infiltration of malicious software onto the computer than may occur via the port.  Therefore, there is a need for a device that renders a port unusable when a user of a computer desires.  The present invention is such a device for a USB port.
