Abstract
An input apparatus for a hand-held electronic device and a computer. The universal input apparatus includes a main connection port, a communication port, an input controller, a communication controller and a route selection unit. The main connection port connects to the hand-held electronic device and the communication port connects to the computer. The input controller provides a plurality of serial input signals. The communication controller, having a serial port coupled to the communication port, is configured to convert the serial input signals into a pair of differential signals transferred through the serial port. Further, the route selection unit establishes a first route between the input controller and the main connection port and establishes a second route between the input controller and the communication controller. Therefore, the serial input signals can be transferred over the first route or the second route alternatively.
