If I understand correctly what you need right now is simply the hookup between the board and the USB connector.
If you look at the pictures in the instructions you can see how it works at the board end of the cable.
At the other end, on my v.2.1 board, the connections are clearly marked: red is +5v, black (or grey) is ground, green is D+ and white is D-.
In case it isn't marked, the pins on the mini USB are, from left to right, blank, blank, D+, D-, +5, with the ground going to the shell I assume. This is with the connector to the top, looking from the connector side of the board.
Hope this helps.
