Mini-USB (Mini-B) was a compact 5-pin connector common on digital cameras, MP3 players, and the original PlayStation Portable in the mid-2000s. USB-IF deprecated the Mini connector family in May 2007, and Micro-USB replaced it in nearly all subsequent compact-electronics designs.

USB4, released August 2019, is built on Intel's Thunderbolt 3 protocol, donated to USB-IF as the new foundation -- up to 40 Gbit/s, a mandatory USB-C connector, and tunneling that lets a single port carry USB, DisplayPort, and PCIe traffic at once. Thunderbolt 3 compatibility is required; Thunderbolt 4 compatibility is optional for device makers.
