Abstract: A hub device and corresponding method include a first chip having at least a first upstream port and a plurality of first downstream ports, a second chip, having at least a second upstream port and at least one second downstream port; and an external memory device, storing firmware data corresponding to the first chip and the second chip. One one of the first downstream ports of the first chip is coupled to the second upstream port of the second chip to form a tiered hub, and the first chip and the second chip are sequentially enabled and the first chip and the second chip sequentially load the corresponding firmware data.
