Abstract
Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits.
