You may have heard of eUSB, the low-voltage cousin to the venerable USB 2.0 from 25 years ago. It's used on SoCs made on small process nodes that can't support standard USB 2.0 voltage levels.
Turns out, it recently got an upgrade called eUSB2V2 (yes, really). It supports asymmetric operation (which is a first for USB) at up to 4.8Gbit/s and is aimed at connecting high-resolution webcams in laptops.
