This slide highlights more generic USB 3.0 considerations and the physical connectors. Most people recognize a USB 3.0 connector by the blue colored insulator (USB 2.0 is white). Another key distinguishing feature on the USB 3.0 B connector and USB 3.0 Micro B connector is that they look as if they are two connectors side-by-side. One side handles USB 2.0 signaling while the other handles USB 3.0 signaling.
