The actual announcement from USB.org [1], I had to go to official source just to make sure this wasn&#x27;t a joke or prank.<p>Why didn&#x27;t they just include it with USB4? It wasn&#x27;t that long ago. But then I checked on Wiki, [2] turns out it has been <i>three</i> years since the release of USB4 spec 1.0.<p>I am not even sure if there are that many USB4 motherboard &#x2F; laptop on the market. I still mostly see USB3.x labels.<p>And USB4 v2, at 80Gbps will be faster than Thunderbolt 4. This reminded me of Anadntech&#x27;s [3] discovery of &quot;Thunderbolt 5&quot; and &quot;USB 80G&quot;. 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?<p>[1] <a href="https:&#x2F;&#x2F;www.usb.org&#x2F;sites&#x2F;default&#x2F;files&#x2F;2022-09&#x2F;USB%20PG%20USB4%20Version%202.0%2080Gbps%20Announcement_FINAL.pdf" rel="nofollow">https:&#x2F;&#x2F;www.usb.org&#x2F;sites&#x2F;default&#x2F;files&#x2F;2022-09&#x2F;USB%20PG%20U...</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;USB4" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;USB4</a><p>[3] <a href="https:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;16858&#x2F;intel-executive-posts-thunderbolt-5-photo-80-gbps-and-pam3-then-deletes-it" rel="nofollow">https:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;16858&#x2F;intel-executive-posts-t...</a>

Ugh, I can&#x27;t wait to find out if &quot;USB4&quot; cables and devices are 1.0 or 2.0.<p>Why not just call it USB5?

So instead of calling it USB4 Gen 2, it&#x27;s USB4 Version 2.0.<p><i>clap</i> <i>clap</i> <i>clap</i><p>Why did I think that USB4&#x27;s versioning would be less messed up than USB 3&#x27;s?

I wasn&#x27;t aware that there&#x27;s a USB Promoter Group which isn&#x27;t the same thing as USB-IF. I guess there&#x27;s a kind of respectable consistency in the corporate&#x2F;legal entities having names as confusing as the technical specifications.

There already is a 2.0! I&#x27;ve been using it for 20 years.

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?
