1. A method for identifying connected devices, the method comprising:
- determining whether a device is connected to an electronic device;
detecting, when the device is connected to the electronic device, a voltage change corresponding to a change of current flowing between the connected device and the electronic device; and
identifying a type of the connected device based on the detection result.

Abstract
A method for identifying connected devices and an electronic device using the method are disclosed. When the connected device is connected to the electronic device, a type of the connected device is identified based on the voltage change according to a change of current flowing in therebetween, and then a corresponding function is performed based on the identified type.
