Take a look at this instructional video and learn how to run a USB cable through existing phone cords. You'll need two phone jacks, a USB extender, and a phone cord. Although dual jacks are featured in this video tutorial, single jacks are preferred. The process is fairly simple, what you need to do is open up the jack and cut the USB extender in half. Strip to the multicolored wires and match up the the wires with the opened phone jack's, all except for the white wire which will go to the yellow phone jack wire. Repeat this process for the second phone jack. Then take the phone cord, make sure that it has four wires inside of it, and hook it up to the jacks. Then plug in the contraption to your computer.
