From CNET: The upcoming USB 4 will restore a useful feature we lost with the technology's modernization: USB hubs that let you multiply the utility of a single port on your PC.
USB, short for Universal Serial Bus, is a remarkably successful standard more than two decades old now. It's spread far and wide, but the newer USB-C technology doesn't work well for one pretty ordinary gadget, a USB hub. These hubs have a cable at one end that plugs into your computer and a number of USB ports to accommodate multiple devices -- a keyboard, mouse, network adapter and memory stick, for example.
USB 4, under development now and due to arrive in products in 2020, should fix that shortcoming, says Ben Hacker, director of USB strategic planning at Intel. He points to USB 4's incorporation of Intel's Thunderbolt technology, a fast though expensive alternative to USB.
"What USB-C was trying to do is become that one [PC and phone] connector to rule them all. It's not quite there," Hacker said at an Intel event Monday. "Our contribution helps it get closer to that."
