USB 3.0 Micro-B cable plug
USB 3.0 also introduced a new Micro-B cable plug, which consists of a standard USB 1.x/2.0 Micro-B cable plug, with additional 5-pin plug stacked on side of it. That way, USB 3.0 Micro-A host connector preserved its backward compatibility with the USB 1.x/2.0 Micro-B cable plugs. However, it is not possible to plug a USB 3.0 Micro-B plug into a USB 2.0 Micro-B receptacle, due to a physically larger connector.
