Abstract
Aspects of a method and system for detecting and identifying electronic accessories or peripherals utilizing a hardware audio CODEC are provided. In this regard, a hardware audio CODEC may be operable to compare one or more voltages on one or more biased pins of an accessory or peripheral port to one or more reference voltages and generate one or more digital representations of the one or more voltages on the biased one or more pins. An accessory or peripheral attached to the accessory or peripheral port may be identified based on the comparison and/or the generated one or more digital representations. The one or more bias voltages may be controlled based on a result of the comparison and/or the generated digital representations. The one or more bias voltages may be reduced after an attached accessory or peripheral has been identified.
