We have a matrix of 2 x 3, with 2 current rating levels (3A max current, or 5A max current), and 3 data speeds (480mbps, 5gbps, 10gpbs).<\/p>\n

Adding a bit more detail, cables 3-6, in fact, have 10 more wires that connect end-to-end compared to the USB 2.0 ones in order to handle SuperSpeed data rates. Cables 3-6 are called “Full-Featured Type-C Cables” in the spec, and the extra wires are actually required for more than just faster data speeds.<\/p>\n

“Full-Featured Type-C Cables” are required for the most common USB-C Alternate Mode used on PCs and many phones today, VESA DisplayPort Alternate Mode. VESA DP Alt mode requires most of the 10 extra wires present in a Full-Featured USB-C cable.<\/p>\n<\/blockquote>\n\n

Inconvenient but not crazy. I’d say the design failure here is the absence of a system of clear graphic symbols to convey this.<\/p>\n<\/blockquote>\n\n

Assuming no one has invented a USB-C hub yet? (USB-C <-> USB-C).<\/p>\n

Still just a bunch of USB-3 hubs or overpriced “docking stations”…<\/p>\n<\/blockquote>\n\n
