Universal Serial Bus 4 (USB4), sometimes erroneously referred to as USB 4.0, is the most recent technical specification of the USB (Universal Serial Bus) data communication standard. The USB Implementers Forum originally announced USB4 in 2019. USB4 enables multiple devices to dynamically share a single high-speed data link.

Thunderbolt 4 and USB4 hubs and docks are the latest technologies in computer connectivity and expansion. They take over from Thunderbolt 3 and USB-C hubs and docks, with significant future-proof benefits while staying backwards compatible with the older connectivity standards.
