Abstract
A universal serial bus (USB) hub for connecting different port types and method thereof are provided. In one embodiment, USB controller detects the power level of each dynamic port to determine whether one of the dynamic ports is connected to the host device wherein the connected dynamic port is defined as upstream port. The disconnected dynamic port of the dynamic ports is defined as downstream port to be connected to the peripheral device. In another embodiment, the USB controller selectively disables the disconnected dynamic port of the dynamic ports. The present invention improves the application flexibility of connecting wire between the hub and the host device.
