Methods and apparatuses relating to resolving roles for dual role serial bus devices are described. In one embodiment, an apparatus includes a serial bus receptacle to receive a serial bus plug of a device, a power supply electrically coupled to the serial bus receptacle, a multiple role toggling circuit to toggle the power supply between a power source role and a power sink role, wherein the device comprises a second power supply to toggle between a power source role and a power sink role, and a randomizer circuit to cause a plurality of different, toggling duty cycles and/or a plurality of different, toggling frequencies to be applied to the multiple role toggling circuit.
