ABSTRACT:
A keyboard/mouse switching controller and method thereof. The present invention is applied to a computer system where a keyboard and a mouse have the same connectors. The present invention determines whether a keyboard and a mouse are coupled to a wrong connector by detecting the keyboard and the mouse using a system BOIS. If a keyboard or a mouse is coupled to a wrong connector, the switching circuit switches the keyboard signal and the mouse signal, thereby transmitting the keyboard signal and the mouse signal to the computer system correctly.
