The full specification is currently in review by over 50 companies, including Intel, Apple, Microsoft, and Texas Instruments. It should be finalised by the middle of 2019, alongside a new and improved USB Type-C spec, with mainstream adoption likely sometime in 2020 as manufacturers start making the move. Here’s hoping the USB Promoter Group keeps the naming simple this time, too. For the record it’s USB4 – just like that.
“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” Brad Saunders, USB Promoter Group chairman, says. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.”
