Microsoft next year plans to update Windows XP to support two technologies left out of the new operating system: USB 2.0 and Bluetooth. Both technologies are used for connecting peripherals to PCs, USB 2.0 at speeds up to 480 megabits per second (mbps) and Bluetooth over the air without wires. USB 2.0 support is expected early next year, and the Bluetooth addition should come by mid-2002.
