Re: Or we can read this as
USB connectors should have a USB logo on the top side. Some of my cables have it, but not all. And the logo's that are there, aren't always easily visible.
And then there are vertically-aligned USB ports. Where the "up" can be either left or right.
Worst of all are the ports at the back of a desktop PC: it's hard enough to try and fit the cable blind without having to wonder if it should be turned over.
