I'd imagine what it does is report to the 360 that a P&C is plugged in and charging, so that the 360 can go into charge-suspend mode when turned off, rather than fully turn off, couldnt do that if it had no data wires.
guys, there is very ver very little data send over the plug and charge kit. the controller is still in wireless mode. if you were to take the RF module off your xbox, and then plug in the controller, you would be able to turn the system on with the guide button, but it will do NOTHING else. no button on the controller will work. the data that is sent via the plug and charge kit i believe is battery state (for auto shutoff) and to switch the system on... nothing else.
which means, the only way to use the wireless controller with a pc is if they make a RF receiver for the computer.
to me it really doesn't make sense why they didn't do this. would have been a real simple thing to do to swap the controller from wireless mode to nonwireless mode, then it would have worked. i don't see why future controllers wouldn't do this and was a missight by MS knowing that more full systems would be sold over the core and more people would want the wireless over the wired. myself personally, I would like to have this option for the very selfdome time I play a pc game, but to me I prefer the wireless controller more, and it's not worth me going and buying a wired controller just for this, I'll still spend the extra $10 to get the wireless.
