Schematic for Making a NULL USB 2.0 Cable?

Does anyone know where I might find a wiring diagram (schematic) for building my own Null USB 2.0 Cable? Never doing things the easy way, I?d like to make my cable for transferring my settings and files to a new computer. ?Yes,? I know there are easier ways of transferring files, but I?d like to give this method a shot if I can make my own cable.
