That's interesting that they added five pins for USB 3.0. I suppose that USB 3 devices then must have to have a mode where they can send their data using only the original four wires (for backwards compatibility purposes), and only use the extra wires if they detect that they are running on a USB 3 port.
Yeah, it's a nice conveinence not needing to buy all-new hardware to fit your USB ports.
Mom got herself a MacBook recently and was pissed off that all it has are two USB-C ports on the side. I'll have to get her a USB hub sometime, seen some decent ones on Amazon that I could probably get for free
But buying the headers as 3.0 or 2.0 had absolutely no significant impact on the final cost of everything, so I figured I should just pick up the 3.0s instead if I want to try making some fast-charge USB condom for my phone. Have yet to get around to that, I'm just hoping that fast-charging doesn't only work if the SSRX/SSTX pins are connected because that involves more soldering and the entire point of it is that the data pins are shorted to stop unwanted data transfer. More research needed.
