US Patent 7629958 Wireless input devices for computer system

A wireless communication system for a computer includes a hub coupled to the computer. The hub includes a first module and a second module, the first module configured to receive commands from one or more wireless input devices, the second module configured to control the first module and interface with the computer. A first wireless input device is configured to be linked to the hub to input a first command to the computer via the hub. A second wireless input device is configured to be linked to the hub to input a second command to the computer via the hub. The hub is configured to support a first operational mode and a second operational mode. The first module transmits the first and second commands received from the first and second input devices to the computer via the second module during the first operational mode. The first module transmits the first and second commands received from the first and second input devices to the computer without using the second module as an interface to the computer during the second operational mode.
