The "branched network pictogram" is indicated in the standard in section 6.5, but there is no requirement that you must have USB-IF certification to use this symbol. I am not able to determine if the USB 2.0 standard has been updated to all web-published USB-IF requirements for marking, so you should probably visit USB.org. Following is from the USB 2.0 standard.
1.4 USB Product Compliance Adopters of the USB 2.0 specification have signed the USB 2.0 Adopters Agreement, which provides them access to a reciprocal royalty-free license from the Promoters and other Adopters to certain intellectual property contained in products that are compliant with the USB 2.0 specification. Adopters can demonstrate compliance with the specification through the testing program as defined by the USB Implementers Forum. Products that demonstrate compliance with the specification will be granted certain rights to use the USB Implementers Forum logo as defined in the logo license. 6.5 Connector Mechanical Configuration and Material Requirements The USB Icon is used to identify USB plugs and the receptacles. Figure 6-5 illustrates the USB Icon. 6.5.1 USB Icon Location 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" 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 6-6 illustrates the typical plug orientation. luck, Brian > -----Original Message----- > From: [email protected] [mailto:[email protected]]On Behalf Of Jim > Eichner > Sent: Friday, April 25, 2008 12:04 PM > To: [email protected] > Subject: USB logos > > > I know USB.org controls use of their USB logos, and you need to get > certification in order to use any of those official USB logos. > > But what about the symbol used to identify USB ports (the branched > network pictogram)?
