KVM switch system and interface adapter for detecting interface of computer

Abstract

A keyboard-video-mouse (KVM) switch system capable of detecting an interface of a computer and an interface adapter used therefor are provided. The KVM switch system includes a computer connector, a processor, and a detecting link. The computer connector is coupled to a computer. The processor is coupled to the computer connector with the detecting link connected therebetween. The processor outputs a first signal to the computer via the computer connector when the processor detects that the detecting link provides a first level and outputs a second signal when the interface adapter is connected between the computer connector and the computer, therefore, the processor detects that the detecting link and the computer provide a second level. The interface adapter has a PS/2 interface and a USB interface. A reserved pin of the PS/2 interface is connected to a power pin of the USB interface.

Dependencies are inferred from the claim text.
