ABSTRACT:
A universal serial bus (USB) power control device includes a universal serial bus control circuit for controlling mutual information transmitted between a computer and its peripheral devices, using data and clocking signals transmitted from a display, a DC--DC converter for processing a power supplied from the display in order to provide an operational power to the universal serial bus control circuit and the peripheral devices, and a universal serial bus power control circuit for detecting a power supplied to the DC--DC converter from the display. If the power supplied from the monitor to the universal serial bus control circuit is abnormal, the abnormal power supplied from the monitor is replaced by normal power supplied from the computer and a message is displayed on the monitor so that a user can recognize that a power supply supplying power to the universal serial bus has failed.
