11. A method of using an electronic device comprising:
-
receiving at least two voltages from a voltage supply line between an external device and a host platform; determining a type of the external device based on the received voltages; and changing a power delivery path between the external device and the host platform based on the determined type of the external device, wherein changing the power delivery path includes operating a first switch to provide power from the host platform to the external device, and wherein changing the power path delivery further includes operating a second switch to provide steady power to the host platform of the electronic device. - View Dependent Claims (12)
