A system and method for optically identifying a component coupled to an electronic device is provided. The method includes emitting light from within the device toward a surface of a component connector inserted into a receiving socket of the device. A light sensor senses the intensity, amplitude or wavelength of light reflected from a surface of the component connector. A processor of the device identifies the component based on the intensity, amplitude or wavelength of light reflected from a surface of the component connector. The processor modifies at least one setting of the electronic device in response to the identification of the component.
