The USB Promoter Group:
The USB Promoter Group today announced the pending release of the
USB4 Version 2.0 specification, a major update to enable up to 80
Gbps of data performance over the USB Type-C cable and connector.
The USB Type-C and USB Power Delivery (USB PD) specifications will
also be updated to enable this higher level of data performance.
All of these specification updates are expected to be published in
advance of this year’s series of USB DevDays developer events
planned for November.
Putting two version numbers in one name is all you need to know about how much clarity this spec brings to the “looks like USB-C but what is it?” realm of cables and ports.
