Vista - Xbox 360 usb controller

i buy an Usb Xbox 360 controller because i spend all my money on my computer
an don't have to buy the console and i like the game pad.... i install the
driver and it work...... but after some time playing counter strike i was
tired of always using the keyboard to chat so i buy a chat-pad for the game
pad but i wont work (no driver for it ) but on the box it is write "Chatting
with friends and family on Xbox Live and Windows-based PCs is easy using the
Xbox 360 Messenger Kit. so i was thinking that i will work... after some
search i found a forum that talk about making driver for it or rewire it to
another keyboard controller to make it work and some that they are just
asking for driver..... but none of them have answer and i really want to
know if some day a real driver will be released for it and when.
