ABSTRACT:
A device and method for identifying an accessory device connected to a first port and a second port of an electronic device by determining an impedance of the accessory device across the first port and the second port is provided. The electronic device generally includes a first port (e.g. a universal serial bus) configured to receive a first connector from an associated accessory device and a second port (e.g. an audio port) configured to receive a second connector from the associated accessory device. The electronic device includes circuitry coupled to the first port and the second port for determining an impedance associated with the accessory device as measured across the first port and the second port. An identification of the accessory device is then made based on the impedance of the electronic device.
