What exactly are the alternative pins used for nowadays? Are they a USB 3.0 addon or a USB 2.0 addon? Very nice post by the way!
-20C isn't too bad unless there's lots of wind, but when you can't wear gloves for the sake of precision (i.e. soldering) it's pretty bad and almost makes you want to just grab the iron to warm up your fingers a bit :/
If by alternative you mean the other 5 pins, one is a second ground pin (the middle one of the five,) and on each side is a separate data stream channel, RX/TX.
I always thought one of the extra five pins was for more power, like for fast-charge devices but I guess that's not the case and they exist solely for faster data transfers, like copying over my entire music library in under an hour to a new drive.
And yeah, those five were new to USB3.0. USB 1, 1.1, 2.0 all had just the four pins, although USB2 for some reason was able to support faster transfer speeds and more power and current, but that was probably because of the technology on the other side of the port.
