Only if you are trying to use the stereo headset adapter I believe. If you aren't using that you shouldn't need to do it.
I think they did at least one that upgraded controller responsiveness. But if the xbox is newer, that's probably already loaded in the controller.
OP, you can just use the mini-usb cable most people have as part of their cell phone charger kit. If you don't have one, ask anyone who doesn't use an iPhone if you can borrow theirs. Hell, given how pervasive they are, someone might just give you one of their spares.
