HUB TRANSMISSION DIRECTION CONTROL METHOD, HUB AND CONTROL CIRCUIT

Abstract: a hub transmission direction control method, a hub and a control circuit are provided. the method includes processes of: detecting a clock signal of a host serial clock line; starting timing when the clock signal meets a trigger condition; when the timed time reaches a preset time, detecting a host data signal of a host data line communicated with a host device and a local data signal of a local data line communicated with a local device; and setting, according to a detection result of the host data signal and the local data signal, a first transmission direction in which data is transmitted from the host data line to the local data line, or a second transmission direction in which data is transmitted from the local data line to the host data line, as a transmission direction between the host data line and the local data line.
