I bought this cable to be able to listen to music with my headphones. But no luck. After a coupleo f weeks, HTC published a driver that should make it work. Kind of strange to publish that driver after they sell the product, don't you agree? However it didn't help either. The installer says i already have the driver installed, and exits. I can use it to charge and connect to the computer, but the phone does not recognise that it has i headphone connected.
I have tried the Expansys forum repeatedly, and others say they have the same problem, but noone answers.
