Abstract: Improved connectivity between a portable communication device and an accessory is provided through the configuration of a USB type interface. Independent control of a mission-critical subsystem and auxiliary subsystems allow for mission-critical audio and push-to-talk (PTT) to be maintained even in the event of a fault condition within the system. The configurability aspect of the interface allows for additional mission-critical input features to be configured into independent mission-critical subsystems.
