On September 4, 2007, Microsoft released a small keyboard accessory called the Chatpad to coincide with the launch of Xbox Live Windows Live Messenger on Xbox 360. It was released as part of the Xbox 360 Messenger Kit, which also includes a wired headset.
The Chatpad connects to the controller via four USB pins located on the front of the controller (wireless or wired), as well as the 2.5 mm jack for headset compatibility.
