Alot of times there's some kind of damage going on with your front-panel USB port or wire going to the motherboard. The damage may not be obvious to spot, but first try to disconnect your front-panel usb from your motherboard and see if the error goes away.
Causes:
Screws used to mount the motherboard are too tight
Rogue mounting bolts attached to your case are touching the underside of your motherboard
Some kind of conductive material is under or on your motherboard causing short-circuits
Wrong installation of front-panel cables
