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.

Abstract: In one embodiment, a method is provided. The method of this embodiment may include detecting, by circuitry that is capable of being coupled to an interface, a level of power transmitted via the interface to the circuitry. If the level of power detected by the circuitry is below a predetermined level, the method of this embodiment may also include initiating transmission of power from a power source to at least a memory comprised in the circuitry. According to this embodiment, when the circuitry is de-coupled from the interface, the memory still may be able to receive the power transmitted from the power source. Of course, many variations, modifications, and alternatives are possible without departing from this embodiment.
