Abstract: In one embodiment, a method is provided. The method of this embodiment may include controlling, at least in part, by a first device, whether a first signal line of a second device is coupled to a bus, and whether a second signal line of a third device is coupled to the bus. The method of this embodiment may also include, after the first and second signal lines are coupled to the bus, supplying from the first device to the second and third devices, via the first and second signal lines, one or more signals that, after being received by the second and third devices, may permit, at least in part, at least one of control and configuration by the first device of the second and third devices. Of course, many modifications, variations, and alternatives are possible without departing from this embodiment.
