Windows XP SP1 does not have USB 2.0 support by default. Windows XP SP2 and later does have USB 2.0 support by default. If your computer has USB 2.0 controllers on-board or installed, you will have to manually install the USB 2.0 Hi-Speed drivers via Device Manager, starting with the USB host controller.
