Abstract
A dynamic power management system for USB hub and method thereof are described. The dynamic power management system includes a host device, a power unit and a hub device. A power management module disposed in the hub device dynamically adjusts the power-supplying statuses of ports in the hub device and further reduces the cost of power transformer externally connected to the hub device.
