Benson Leung (via Hacker News):
We have a matrix of 2 x 3, with 2 current rating levels (3A max power or 5A max power) and 3 data rates (480mbps, 5gbps, 10gpbs).
If you add a little more detail, cables 3-6 actually have 10 more wires that connect end to end compared to the USB 2.0s to handle SuperSpeed data rates. Cables 3-6 are called "Full-Featured Type-C Cables" in the specification, and the extra wires are actually required for more than just faster data rates.
"Full-Featured Type-C Cables" is required for most common USB-C alternative modes used on PCs and many phones today, VESA DisplayPort Alternate Mode. VESA DP Alt mode requires most of the 10 extra wires included in a fully-featured USB-C cable.
Uncomfortable, but not crazy. I would say that the design error here is the absence of a system of clear graphic symbols to convey this.
Provided no one has invented a USB-C hub yet? USB-C
Still just a bunch of USB-3 hubs or overpriced "docking stations" …
