Abstract
Power management techniques for a Universal Serial Bus (USB) include determining an idle period on one or more USB ports by a main controller circuit of a USB host controller. The main controller circuit signals a suspend to a Power Management Controller (PMC) sub-circuit of the USB host controller, in response to the determined idle period. The PMC sub-circuit stores one or more operating parameters of the one or more USB ports in response to the suspend signal. The PMC sub-circuit also maintains the idle state on the one or more USB ports in response to the suspend signal. Thereafter, the main controller circuit is placed in a low energy state while the PMC sub-circuit maintains the idle state.
