Abstract
Two super-speed lanes may be enabled on a single USB cable. In an exemplary, non-limiting aspect, the USB cable is a Type-C cable. In further non-limiting aspects, the super-speed lanes may be present even if there is no USB 2.0 lane present on the D+/D− pins of the USB cable. Use of the second super-speed lane increases data throughput. Eliminating the requirement that the D+/D− pins be used for USB 2.0 data allows greater flexibility in the use of the USB connection because audio or video data may be sent over the D+/D− pins instead of USB 2.0 data. Further, the use of the two super-speed lanes allows a single computing element to operate as a host on one lane and a device on a second lane.
