USB speeds | The Verge https://www.totalphase.com/blog/2020/01/naming-and-branding-changes-behind-superspeed-usb/

It has been revised several times.

In 2019, the USB Promoter Group announced the USB4 specification, which offers a substantial increase in signaling speed Ð up to 40 Gbps using a dual lane operation within a Type-C cable. With this newly introduced USB spec, it will provide a new opportunity for USB-IF to create a clear brand that distinctly indicates USB performance moving forward.

In 2020 the final USB 3.2 specification comprises of all prior 3.0 and 3.1 specifications and encompasses all three speeds: 5 Gbps, 10 Gbps, and 20 Gbps. For marketing and branding purposes, the SuperSpeed USB packaging logos include these performances for easier adoption by consumers:
