Here's my take on how to identify USB 3.0 ports:
All USB 3.0 ports & cables that I've seen have blue inserts.
Also, in Device Manager if you expand Universal Serial Bus controllers and see...
"Universal Host" ... your port is version 1.1.
Both "Universal Host" and "Enhanced Host" ...your port is version 2.0.
"USB 3.0" ...your port is version 3.0.
In the days of my youth,
I was told what it means to be a man.
Now I've reached that age
I've tried to do all those things the best I can.
