Step 2: Desolder USB attachment
You will need a soldering iron, solder, copper wire, pliers, and a wet sponge.
(1) I found it works best to add clean solder to the soldering iron, then clean it with a wet sponge(while hot).
(2) Heat the individual solder points, letting the solder absorb onto the iron or onto copper wire. In this manner you can break the connection points.
(3) Once you have the solder removed, the USB connector should easily fall away from the board.
