If "any device" doesn't include the joystick, it's not "any device" but "some devices". That leads to 2 questions:

1. What devices exactly do give this message, and what don't?
2. What do the other USB 3.0 ports (other ports than "this particular port") say if you plug one of that "some devices" in?

I don't think this is a Windows 7 issue. I think it's a hardware issue.

There is no fix

There is no fix. Either your USB 3.0 devices are bad, trying to draw too much power from the USB port, or the USB 3.0 hardware is bad and not able to supply as much power as it should. If you get the same error with multiple devices on the same port, my money would be on the port and associated hardware being the problem. In which case the only fix is to replace the USB 3.0 controller and/or port, which generally means replacing the entire motherboard unless you have a USB 3.0 controller add-in card.

It's a very old issue.

If you do your research you discover that Dell had some models that did this on USB 2.0 and it was nothing really wrong. That is, those PCs just reported it a little earlier than most.

There is a way to turn it off, but given no make or model, I'll write you should do your research or just return this port as defective.
