Definition: USB 3.2


The previous USB standard (the latest is USB 4). Introduced in 2017, USB 3.2 added two dual-lane SuperSpeed+ modes when using USB Type C cables. USB 3.2 also absorbed the previous 3.0 and 3.1 specifications by adding a confusing "Gen x by x" label (see below), at which time USB 2.0 and 3.2 became the two official USB specifications. However, there are millions of ports labeled USB 3.0 and 3.1 in use on computers, hubs, storage drives and other components. With the USB 4 introduction in 2019, the naming was thankfully simplified (see USB). See USB Type C, USB 3.0 and USB 3.1.
