A method and system provides current, from an electrical hub, to a device. The method and system further receives, at the electrical hub, an indication that the device is in a first configuration state of a plurality of configuration states. An example includes detecting, at the electrical hub, a detected current value of the current sent to the device. Processes include determining, at the electrical hub, whether to generate an error indication based on a comparison of the detected current value and a first reference value or range of values associated with the first configuration state.

A method for detecting a media device comprises generating a waveform on a bias node of a demonstration system. The waveform has a fundamental frequency that is greater than a maximum frequency of a media frequency range of the demonstration system. The waveform is rectified to produce a detection signal. An impedance between the bias node and a ground is modified in response to a coupling of the media device to the bias node. An output signal changes state in response to a change in the detection signal due to the modification of the impedance.
