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.

Abstract: An interface chip capable of accurate link detection. The interface chip mounted on a first electronic device has a link layer and a physical layer. The link layer outputs data to be transformed and transmitted to a second electronic device by the physical layer. The data transmitted from the second electronic device is received and transformed by the physical layer and then conveyed to the link layer. The link layer includes a state machine, which performs a state modification on the first electronic device to rescue the second electronic device from a trapped state for confirming a link between the first and second electronic devices, wherein data output by the link layer and transformed and transmitted to the second electronic device by the physical layer is changed according to the state modification.
