US Patent 11013987 Information handling system controller scalable interface

A portable information handling system interacts with a game controller through either a direct connection at a wired interface at the sides of opposing controller housings and the information handling system housing or through a bridge having a bridge housing that directly couples to the controller housing as a bridge to the information handling system, such as with a wireless interface. During a sliding coupling motion, pins of the controller housing wired interface move across pins of the bridge or information handling system wired interface. Analysis of the interface signals through a sliding coupling motion identifies the type of controller housing, such as a controller housing with game input devices or with extra functions like speaker audio and supplemental battery power.
