Step 2: Desolder USB attachment

In order to use the USB, you will need to first desolder the connections to from the circuit board to the USB connector.  The connector has 4 points of connection on Side A(positive/negative and D+/D-) and 2 points on Side B(case ground). 

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.
