Different USB 2.0 ports?

I have two USB SS 2.0 ports on the back of the Xbox One, but they differ slightly in terms of their metal shape. I would like to know whether one connection is better than the other.

You can see different metal deformations. The upper connection has one more slot than the lower one.

Is it what is what in the manual.

Use google if none is available.

looks normal to me.

I used one without instructions. But I also think it doesn't make any difference. I've searched the internet before, but since there's nothing about it, I think it's irrelevant too.

That's why I say google. The handbooks can all google and download as pdf.
