I looked on this forum http://www.ntcompatible.com/thread32356-1.html and read about shutting down completely and removing power.
I shut down my laptop removed the battery and held down the power/startup button for 30 seconds and it has fixed the problem.

I've the same problem and this solved it.
Unfortunately the driver, "Virtual USB Hub," was accidentally deleted during my tingling on the device manager.
OS Windows 7 Home
Can someone please tell me where to obtain "Virtual USB Hub," driver so I can install it back?
