Why does USB have two seemingly unrelated versioning schemes? There's USB 1, 2, 3 and now 4 as well as Type A, B and C. This mess looks like manufacturers wanted to create a way to trick the average customer into buying the wrong cable or adapter, whereas initially the reason for creating USB was to increase compatibility.

> Why does USB have two seemingly unrelated versioning schemes? There's USB 1, 2, 3 and now 4 as well as Type A, B and C. They decoupled the standards for the protocol and the connector. "USB C" is just a port/connector shape -- there's no guarantee that any cable or port that is USB C shaped supports any version of USB-the-protocol. This is the case with eg) dedicated Thunderbolt 3 ports and cables. It's every bit as silly and confusing as it sounds in practice.

  And I forgot to mention the mini and micro versions of USB ports, which add to the overall confusion.

    There is also the USB 3 versions of mini and B which don't fit in the USB 2 ports. This is part of the reason I have an entire draw dedicated to different USB cables.
