The next is the way it all works:

The USB-antics IF’s have a way to them. As a way to maintain issues fixed, every new commonplace incorporates the earlier generations as a part of that spec. Because of this, when USB 3.1 was launched, the prior 3.0 specification was renamed USB 3.1 Gen 1 and the brand new, sooner 3.1 specification was renamed USB 3.1 Gen 2.
Equally, now that USB 3.2 is out, these numbers are being renamed USB 3.2 Gen 1 and USB 3.2 Gen 2.

As a result of producers can now conceivably model something a USB 3.2 port even when it solely delivers USB 3.0 period, 5Gbps velocity via a USB Sort-A connection, the USB-renaming IF’s is more likely to trigger some extra confusion.
Though the USB-IF stresses the need of producers precisely describing their {hardware} capabilities in advertising and marketing, it’s going to seemingly be as much as customers to find out whether or not they’re getting “real” USB 3.2 speeds or simply rebranded earlier specs. Nonetheless, the truth that the USB-IF has finalized nomenclature means we’re one step nearer to seeing this sort of gear arrive, which might solely be a very good factor for anybody wishing for faster cords.
