Hardware manufacturers are supposed to create standards associations to make things easy for users, and to avoid incompatibilities and headaches. In the case of the USB Implementers Forum , USB Implementers Forum (USB-IF), it is just the opposite. Today the USB standard is a complete nonsense gibberish that confuses everyone . And the thing is going to get even more complicated. In the MWC 2019 in Barcelona have introduced the new USB 3.2 standard , along with a change of name of USB 3.0 and USB 3.1, which disappear to be called USB 3.2 … Does anyone understand?
The new USB Type C reversible was going to be the panacea that would solve all the problems of the USB connector, but it has been the opposite. USB TIpo C refers only to the shape of the connector or the plug, but inside the cable can be USB 2.0, 3.0 or 3.1, can take or not video, and can recharge devices with different amperage.
As well as bad cables are sold without protection, the result is that there are USB Type C cables that can damage the laptop during the recharge , others that charge slower according to the amperage, others that do not carry video when you thought so, or that are slow (USB 2.0), when you thought you had bought a cable of last generation. To complicate things further, USB 3.0 and 3.1 disappear, and now we have three types of USB 3.2. Bravo!
The USB-IF association has presented today at the MWC 2019 in Barcelona the new USB 3.2 standard, which reaches speeds of up to 20 Gbps.
USB 3.2 is compatible with current cables, and even some SuperSpeed USB cables that until now were going to 5 Gbps, when using them in a USB 3.2 connector can double the speed to 10 Gbps.
Another important novelty is that the names USB 3.0 and USB 3.1 disappear, and now they are called USB 3.2 , according to this conversion:
- USB 3.2 Gen 1 : is the new name of USB 3.1 Gen 1, which some companies called USB 3.0. It reaches 5 Gbps and its new commercial name is SuperSpeed USB .
- USB 3.2 Gen 2 : is the new name of USB 3.1 Gen 2. It reaches 10 Gbps and its new commercial name is SuperSpeed USB 10 Gbps .
- USB 3.2 Gen 2×2 : it is a new standard, which did not exist until now. It reaches 20 Gbps and its commercial name is SuperSpeed USB 20 Gbps .
The first boards with USB 3.2 Gen 2×2 connectors will arrive this summer, but peripherals and cables may not see them until next year. If by then they have not changed it again …
