2 days ago I suddenly started getting a USB DEVICE NOT RECOGNIZED error.  Says, "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."  Its showing an "Unknown USB Device" under the USB Root Hub (6 ports).

Now the problem is, I don't have anything plugged into any of the USB ports.  The USB ports have power to them but don't recognize anything that is plugged in.  For example, my phone will charge but iTunes doesn't launch.  The IR light on the mouse lights up, but the mouse doesn't work etc etc.  This occurrs regardless of which USB port I use.

I've tried restoring to a date before the error started and I still get the error.  I've updated the chipset as well as flashed the bios also.  Device Manager shows everything working properly and all drivers up to date but the error still pops up and nothing works.  

Any help is greatly appreciated.
