Abstract
Abstract Computer systems provide separate ports for USB (Universal Serial Bus) and PS2 peripherals. Unfortunately, this arrangement requires the computer to have two separate wireless transmitters to communicate with wireless USB and PS2 peripherals. Accordingly, the present invention provides a device, a method, and a system for combining PS2 data and USB data into one serial data stream, thereby enabling one wireless transmitter to serve both a PS2 and a USB peripheral. Specifically, one embodiment includes a PS2 port for receiving PS2 data; a USB port for receiving USB data; a data combiner, coupled to the PS2 and USB ports, for combining the PS2 and the USB data; and a wireless transmitter, coupled to the data combiner, for broadcasting a wireless signal carrying combined PS2 and USB data. In one embodiment, the data combiner includes a processor and a memory that stores unique data-combining software.
