Abstract
A user device determines whether a device connected to its headset jack is an audio accessory device. If the device connected to the headset jack is an audio accessory, the user device connects one or more pins of the headset jack to an audio codec. If the device plugged into the headset jack is not an audio accessory device, the user device connects one or more pins of the headset jack to alternate circuitry. The user device then determines, through the alternate circuitry, an electrical operating parameter requirement of the accessory device, and provides, from the alternate circuitry, the required operating parameter to the accessory device through the headset jack. The alternate circuitry may include an adjustable voltage regulator and/or an adjustable current regulator and the required operating parameter may be one or more of a voltage supply and a current supply.
