Abstract
The present invention relates to an apparatus and method of a Universal Serial Bus (USB) device to control power supply for USB devices coupled to a host through a USB and to control power supply for the coupled USB devices based on whether the USB devices are operative. A power supply controlling apparatus and method can interrupt power supply for an USB internal circuitry and other coupled USB devices if a state of signals on corresponding data lines coupled to a host represents inoperative state of the host or individual USB to reduce or prevent overall power consumption.
