|説明:||The USB Icon is embossed, in a recessed area, on the topside of the USB plug. This provides easy user recognition and facilitates alignment during the mating process. The USB Icon and Manufacturer’s logo should not project beyond the overmold surface. The USB Icon is required, while the Manufacturer’s logo is recommended, for both Series “A” and “B” (or “mini-B”) “B” plug assemblies. The USB Icon is also located adjacent to each receptacle. Receptacles should be oriented to allow the Icon on the plug to be
visible during the mating process. Figure 6-6Figure 6-7 and Figure 6-8 illustrates the typical plug orientations.
