I am officially crying "UNCLE" now.

I also think a USB 2 cable would work, certainly physically, in a USB 3 socket but you just wouldn't get the signal/speed benefits of USB 3 throughput.

This article seems to bear this out: https://technewsdaily.com/news/is-a-usb-3-0-compatible-with-usb-2-0/

And several users of the cheap Sanoxy cable report using it okay with USB 3.

But if this is true, then WHY would Sanoxy, in the Amazon ad, per my previous post, CLEARLY state: "The MIDI Cable can support WIN10, but must use in USB 2.0 port, ("NOT FOR USB 3.0 PORTS)"

Now I have misgivings about ordering on Amazon the FORE $19 cable that has 4,500 orders and a 4.4 star rating but only refers to USB 2.0 (even though some users report using it with USB 3). I guess I'll order it and return if it doesn't work...
