"Works" may be a spectrum, but "works optimally" is binary. There is so much variation in the USB spec that a data transfer or a battery charge could take a few minutes or a few hours depending on which cable and which port/adapter you use, with no foolproof way to make sure you're putting together the right equipment, because regardless, it still "works", just not very well. Don't get me wrong, it's great that it "works". I just wish it was clearer what I need to make it work optimally, aside from just using the one brick and cable that came with my device (assuming I was so lucky).
