Type USB in to the parts search bar (the magnifying glass in the parts bin) and hit enter and a variety of USB connectors A, B, mini, micro male female (without the cable) and most anything with a USB connector will come up. One with a cable would be more difficult to do as Fritzing doesn’t support multiple connections in a single cable so you would need to drag seperate wires between the connections. If all you want is to show connectivity in breadboard a couple of parts could be made to take a wire that doesn’t connect to anything between them, but it won’t show in schematic or pcb. It depends what you are trying to do with the USB cable. If you want a full connection in all three views the connectors are your answer.
