Yes you can clean them up its online and its pretty simple not that I
recall what it was. I had the same issue and in device manager essentially
the hanger ons are hidden devices once you tell device manager to show
hidden you will see the issue.
I do not recall if you right click and release or what.
But it was online and a common issue.
