Yes. You plugged into one of the two front ports. Those are 1.0 ports identified by the white plastic.
When I started, I did not know that and plugged the keyboard and the trackball into the front two ports.
Since the 3.0 card was handy and I didn't know better, I plugged the USB, 3.0, blue plastic into one of those ports. They were seen by the computer, so I didn't give it another thought.
Then you suggested that I needed to use a 2.0 or slower. I didn't know how to identify the difference so I looked it up. White, 1.0; black, 2.0; blue, 3.0.
And I found that the two front ports were white, as were the original USB ports at the back. Once that was identified the process went forward.
I followed the procedure too, but unlike you, I put the USB stick in the wrong location.
