Abstract
An automatic interface identification technique for an apparatus capable of supporting both USB and PS/2 interfaces comprises connecting a detector to first and second ports provided for the apparatus connected to a host computer through a USB or PS/2 interface. The detector has an interface detect function including a logic confirming mechanism and an interface identifying algorithm and a mode select function receiving first and second control signals such that the logic confirming mechanism is connected to the first and second ports by the interface detect function to detect the logic states of the first and second ports in association with the interface identifying algorithm to thereby correctly identify a USB or PS/2 interface is connected and to further determine USB or PS/2 mechanism in response to signal transmissions.
