A plug-in device detection module includes a measurement signal generator for generating a measurement signal. A port coupler couples the measurement signal to a selected plug-in receptor of a plurality of plug-in receptors, generates an input/output signal and generates a port signal in response to the measurement signal. A reference signal generator generates a reference signal based on the input/output signal, the reference signal having a plurality of reference signal values. A detection module detects a plug-in device type of a plug-in device coupled to the selected plug-in receptor, based on the reference signal and the port signal.
