USB Promoter Group Announces USB4 Version 2.0 with 80Gb/s Transfer Speeds

Because manufacturers of actual products are in the USB forum and actively lobby for this shitty naming convention, so their sales of USB4 products don't drop.

Same reason, same companies, same lobbying, which gave us USB 3.0, USB 3.1 Gen 1, USB 3.1 Gen 2, USB 3.2 Gen 1, USB 3.2 Gen 2, USB 3.2 Gen 1×2, USB 3.2 Gen 2×2 (yes they all exist).

Will they be banned from sale in the EU because of the phone charger mandate or did that not actually pass into law? Or is there something about backwards compatibility through USBC that’s bypassing it?

So instead of calling it USB4 Gen 2, it's USB4 Version 2.0. clap clap clap Why did I think that USB4's versioning would be less messed up than USB 3's?

I look forward for the word salad that is USB4 V2.0 (2x2)^2!

It will still use USB-C, yes

I wasn't aware that there's a USB Promoter Group which isn't the same thing as USB-IF. I guess there's a kind of respectable consistency in the corporate/legal entities having names as confusing as the technical specifications.

There already is a 2.0! I've been using it for 20 years.

The actual announcement from USB.org [1], I had to go to official source just to make sure this wasn't a joke or prank.

Why didn't they just include it with USB4? It wasn't that long ago. But then I checked on Wiki, [2] turns out it has been three years since the release of USB4 spec 1.0.

I am not even sure if there are that many USB4 motherboard / laptop on the market. I still mostly see USB3.x labels.

And USB4 v2, at 80Gbps will be faster than Thunderbolt 4. This reminded me of Anadntech's [3] discovery of "Thunderbolt 5" and "USB 80G". So will the next version be called Thunderbolt 4 v2? If not, why not just call this new 80Gbps USB ( likely many changes in PHY ) USB5?
