I was having this same issue and it took me hours to figure out.
I'm a little late on this thread, but for anyone else who comes across looking for answers.
For starters, even though the guide tells you not to use USB 3.0, for me it was wrong.
1. Uninstall the drivers/Universal Control and reinstalled them while connected to a USB 3.0 port
2. Restart your computer
3. Follow the instructions in this video.
(Be warned, they are in serious need of a pop filter.)
If for some reason that link no longer works, google search "power management on USB devices windows 10"
And yes I use Google as a noun not a verb, but only because it makes me feel superior to everyone else.
