As that didn't work it must be the Arduino. Are you able to lift the board in the case and move the USB extension to the other USB on Arduino. The 2nd port is called a Native port, you can't view the serial monitor on this port but you can program. Before programming in the IDE for board type select the Due that says Native USB port beside it and the com port should say Native as well.
