1. A universal interface comprising:

  • a microcontroller;

    a detection line coupled to said microcontroller, wherein said detection line is configured to sense a voltage at a port of a host computer coupled to said universal interface;

    a crossbar switch coupled to said microcontroller, wherein said crossbar switch is configured to establish a data communication link between said universal interface and a first type port of said host computer, wherein said crossbar switch is enabled to establish said data communication link between said universal interface and said first type port of said host computer upon said detection line sensing a first logic state; and

    a transceiver coupled to said microcontroller, wherein said transceiver is configured to establish a data communication link between said universal interface and a second type port of said host computer, wherein said transceiver is enabled to establish said data communication link between said universal interface and said second type port of said host computer upon said detection line sensing a second logic state.
