thanks zhp43867

i'd like to point out something about the Rolf Resler interface (at least the USB version) for anyone having trouble getting it to work.

i don't have my steering wheel controls working as of yet, but according to Driiven, getting the interface to function properly requires the use of a constant +12v and ground in conjunction with the normal IBUS pin of the 3-pin connector in the trunk. the power and ground provided by this 3-pin connector may function with the serial version of the interface, but due to initialization issues the USB version won't function properly and quirky things with your lighting system can occur unless you use a constant power and ground.
