The name of the USB will be a little easier to understand – Engadget


The organization USB-Implementers Forum (USB-IF), which is responsible for developing the USB specification, has changed the USB naming specification slightly, hoping it will make it easier for users to understand. The “SuperSpeed ​​​​​​​​” and “USB4” that were originally in the name will disappear, leaving only the speed, so “SuperSpeed​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ takes. “USB4 20Gbps” also becomes “USB 20 Gbps”.

USB-IF said that this is mainly because the use of names like “SuperSpeed” has become difficult to describe the capabilities of the specification. Anyway, if the speed is added anyway, then these names have become cumbersome. Interestingly, this does not extend to USB 2.0 called “Hi-Speed” because with the same logic it should be renamed “USB 480Mbps”, USB-IF is worried that users will think 480 is faster than 480Mbps 20 or 10 more and therefore misleading. At the same time, the cable icon will also be replaced. In addition to showing the maximum speed, it will also show the maximum supported charging wattage.

However, due to the open nature of the USB-IF specification, with the exception of a very small number of products seeking certification by the USB-IF, there is no mandatory use of the name, and manufacturers can call them whatever they want. And to be honest, it doesn’t solve the problem of the confusing naming of the current USB specification itself, especially the USB 4 Version 2.0 launched by USB-IF itself last month, which broke the naming convention in the period USB 3.0, which is extremely annoying.

The explanation of USB-IF is that for ordinary users, the naming method that only shows the speed will avoid the problem of the USB specification below, but still, there are too many additional specifications for USB, such as DisplayPort mode , charging PD, etc., and this nomenclature fails to accurately convey this information. In the end, USB still requires users to do their own homework to understand what capabilities their devices support.
