Claim:
1. An electronic device operable to receive power from external equipment having a resistance, the electronic device comprising: a connector having a pair of power line contacts and first and second data line contacts, wherein the first and second data line contacts are configured to be electrically coupled to opposing sides of the resistance of the external equipment when the connector is in contact with the external equipment; and control circuitry configured to measure the resistance of the external equipment by transmitting a signal to the external equipment using the first data line contact while the connector is in contact with the external equipment, wherein the control circuitry is further configured to advertise to the external equipment that the electronic device has capabilities that extend beyond standards-compliant capabilities by pulsing the signal to generate signal pulses and transmitting the signal pulses to the external equipment using the first data line contact while the connector is in contact with the external equipment.
