Forget USB 3.2: Thunderbolt 3 Will Become the Basis of USB 4

USB 3.2 Gen 2×2 isn't even my final form:

Fulfilling its 2017 promise to make Thunderbolt 3 royalty-free, Intel has given the specification for its high-speed interconnect to the USB Implementers Forum (USB-IF), the industry group that develops the USB specification. The USB-IF has taken the spec and will use it to form the basis of USB4, the next iteration of USB following USB 3.2.

Thunderbolt 3 not only doubles the bandwidth of USB 3.2 Gen 2×2, going from 20Gb/s to 40Gb/s, it also enables the use of multiple data and display protocols simultaneously. We would expect the USB4 specification to be essentially a superset of the Thunderbolt 3 and USB 3.2 specifications, thus incorporating both the traditional USB family of protocols (up to and including the USB 3.2 Gen 2×2) and the Thunderbolt 3 protocol in a single document. Down the line, this should translate into USB4 controllers that support the whole range of speeds.

Lost? Frightened? Confused? Good!

    Will this make it easier to jailbreak future iPhones? (When they switch to USB C)

    What could possibly [soylentnews.org] go wrong

    That's not a bug, that's a feature.
    I mean, look, you really like FBI to waste you tax money on Cellebrite instead of buying them cables straight from ebay [soylentnews.org] at Chinese prices?

    (grin)
