Most of the threads on this error are old, (2015) so I am starting a new one. I only notice it when I happen to be in the device manager. I have no problems with any of my connected USB devices (that I have observed).
I have tried uninstalling it, and rescanning and it pops up again, so apparently it is something that is connected. Without disconnecting All of my USB devices one at a time (which I am wont to do, as it is not bothering me, other than that it is there!) It has been there for quite a while, so apparently is not anything new being connected.
Is there no way to identify WHAT is connected to this port, or even what port it is?
BTW, it only shows up in the USB Controller section, no matching errors in any of the devices themselves!
Curiouser and curiouser...
