When USB 3.0 came out in 2008 it had a max speed of around 5 Gbps. However, when USB 3.1 came out in 2013 with a max speed of 10 Gbps, the 5-Gbps version was renamed to USB 3.1 Gen 1, while the new, faster spec was USB 3.1 Gen 2. Confused yet? Well, it gets worse. When USB 3.2 came out in 2019, the 5-Gbps USB was rebranded again to “USB 3.2 Gen 1,” the 10-Gbps version became “USB 3.2 Gen 2,” and the new 20-Gbps spec became—you guessed it—USB 3.2 Gen 2x2. … Wait, what? The “2x2” refers to running two 10 Gbps lanes of data simultaneously and … you don't need to know all of this. Many hub manufacturers have given up on names, labels, and symbols. They've just started printing the maximum speed next to ports directly.
