The connector (122) includes an information pin (124) to receive information generated from operation of the accessory (104). The controller (108) identifies the accessory (104) from a voltage level generated by attachment of the accessory (104) to the information pin (124). Also, an accessory identification apparatus (195) used in an accessory (104) includes a connector (173) to couple to an electronic device (102) and an identification element (174) coupled to the connector (173). The connector (173) includes an information pin (179) to supply information generated from operation of the accessory (104). The identification element (174), upon attachment of the connector (173) to the electronic device (102), provides an identity of the accessory (104) via the information pin (179).
