ABSTRACT:
An integrated input device communicates with a host computer system in accordance with the low-speed Universal Serial Bus (USB) Specification. The keyboard includes a function controller for providing output signals to a host computer or an upstream hub using a single USB low-speed cable and a USB type A connector. Signals generated by a pointing device are coupled to the appropriate pins of the function controller. The pointing device may be hard-wired to the function controller. Alternatively, the signals generated by the pointing device may be coupled to the function controller using a wireless technique, such as a radio frequency technique or an infrared technique.
