    Abstract: An electronic device includes a first stream port and a control circuit. The first stream port includes a plurality of lanes, wherein the plurality of lanes are used to couple to a plurality of lanes of a second stream port of another electronic device, respectively. The control circuit is coupled to the first stream port, and is arranged for controlling a data transmission and data reception of the first stream port. When the lanes of the first stream port receive training sequences having a plurality of lane numbers from the lanes of the second stream port, respectively, to initiate a lane number negotiation, the lanes of the first stream port send back the received lane numbers to the second stream port, without considering default lane numbers of the lanes of the first stream port.
