USB-IF Association Updates USB Naming and Logo
As the most common computer electronic product interface, USB has already penetrated into all aspects of life. In the past two decades, after several protocol updates, USB interfaces have had different data transmission rates and power supply standards. I believe that many users will be dizzy about various USB 3.0/3.1/3.2 interfaces. With the arrival of the USB4 2.0 specification, many users fear that the situation will become more confusing.
Recently, the USB-IF Association announced that it will update the naming and logo of USB so that users can understand the situation of the USB interface of the device more quickly and clearly, and purchase products that meet the requirements. The new rules will go into effect this quarter and may appear on new products at the end of the year.
The original logo with “SuperSpeed” will no longer be used, and there will be no such name as “USB4“. It will be replaced by “USB+Speed”, and there will also be charging power. The new logo is mainly divided into three types: USB Type-C® Cable Logos, USB Charger Logos, and Performance Logos, which greatly simplifies the related naming and identification difficulties.

Among them, USB 3.0, USB 3.1 Gen1, and USB 3.2 Gen 1 will be unified as USB 5Gbps; USB 3.1 Gen2 and USB 3.2 Gen2 will be unified as USB 10Gbps; USB 3.2 Gen2x2 changed to USB 20Gbps; USB4 changed to USB 40Gbps. If the cable is compliant with the USB Power Delivery (USB-PD) 3.1 standard and can provide 60W or 240W of power, the corresponding wattage will be indicated.
According to the USB-IF Association, certified cables in the future will indicate the data transfer rate and charging power, and users will no longer need to look up parameters for various standards. However, it is important to remind that not all devices or cables are certified.
