USB 1.1, released in September 1998, was the first widely adopted USB standard -- 12 Mbit/s Full Speed for most peripherals, with a 1.5 Mbit/s Low Speed mode for mice and keyboards. The original USB 1.0 from January 1996 saw little real-world adoption before 1.1 quickly superseded it.

USB 3.2 Gen 2x2, part of the USB 3.2 specification released in September 2017, is the only tier in the 3.2 family that's genuinely new hardware rather than a renamed predecessor -- it doubles Gen 2's 10 Gbit/s by running two lanes simultaneously, reaching 20 Gbit/s, but only over USB-C connectors and cables wired for it.
