USB-IF confusingly merges USB 3.0 and 3.1

USB branding has become more confusing

The USB standard has just gotten even more confusing for end users. If you know the difference between USB 2.0, USB 3.0, USB 3.1 Gen 1/Gen 2, we are sorry because things have been changed once again. The USB 3.2 standard has been announced and it'll include both USB 3.0 and 3.1.



According to USB-IF, the new USB 3.2 standard provides a whopping 20Gbps of throughput. At the moment this is the only clear information that we have. The USB 3.2 merges the previous specifications and makes them part of its own. The full name of the new standard is "USB 3.2 Gen 2x2".

USB 3.1 Gen 1 (formerly known as USB 3.0), which offers speeds up to 5 Gbps, will be rebranded into USB 3.2 Gen 1 while USB 3.1 Gen 2, which supports speeds up to 10 Gbps, will be called USB 3.2 Gen 2. Since USB 3.2 has double the throughput of USB 3.1 Gen 2, it'll be called USB 3.2 Gen 2x2. Last but not least, we’ll find also SuperSpeed USB 3.2 names that will refer to the marketing names. These new specifications refer only to throughput speed. The connector should be the same, although we are still in a gradual transition from USB-A to USB-C.

The USB-IF paper outlining the new specs explains several times just how important it is for manufacturers to indicate clearly how fast the USB device or port is. At the moment, there isn't really nothing that prohibits a laptop manufacturer from simply calling a port "USB 3.2" without adding any further detail. This is just an example of course.

At this time it's hard to say when USB 3.2 devices will arrive.
