摘要： The present invention relates to an apparatus and method for controlling power to a Universal Serial Bus (USB) device. The present invention provides an apparatus for controlling power to a USB device, the USB device being used to connect a Personal Computer (PC) with a peripheral device, the power control apparatus including a plug-in port for connecting the peripheral device with the PC, a state detector for detecting whether the peripheral device is in a preparation completion state, a power supply unit for supplying power to the USB device, and a power control unit for controlling the power supply unit so that power is supplied to the USB device if it is determined that the peripheral device is in a plugged-in state, and if it is determined that the peripheral device is in a preparation completion state by the state detector. Accordingly, the present invention performs the supply of power only when the peripheral device is plugged into the USB device and its internal application program is in a preparation completion state, so that it can prevent power from being unnecessarily consumed.
