A USB(Universal Serial Bus) cable apparatus is provided to reduce a manufacturing cost and make the apparatus conveniently managed by integrating various kinds of USB cable apparatuses in one USB cable apparatus. The first port(31) is coupled to the first electronic device(10) which supports a USB OTG(On-The-Go) interface. The first port includes the first communication line including the first ID(Identification) line and the first power line including a ground line. The second port(32) is coupled to a USB interface of the second electronic device(20). The second port includes the second communication line including the second ID line and the second power line including the ground line. A port switch(33) is coupled to the first and second ports. The port switch selectively connects one of the first and second ID lines to the ground line and connects the first and second communication lines to the first and second power lines.
