Considering a used F1 style rim and USB button box I have the opportunity to pick up. It's compatible with the V2 quick release (which I have two spares of.) Only question is connectivity - it uses a standard USB coiled cable. Does the V2 stock button box use any kind of proprietary signaling through the base or is it just pass-through USB that happens to use RJ12 connectors?
I can run an independent USB cable and mount a box to the side of the V2 wheel housing, but I'd rather not if I can use an RJ12 to USB coiled cable.
