Unable to locate any drivers for my USB devices  

Hi awj. I have unbelievable similar issues that i have just about given up on. Did you ever come up with anything to work??
Thanks in advance

@anderson9385 - the only thing I could do to make it work was to do the repair install.

This isn't as difficult as it sounds, and like I said, the only things I had to change were my wallpaper, Windows updates, and some custom folders in my start menu. It puts your OS back to how it was when you installed it, though surprisingly - as I like to use a fair amount of custom hacks on my system - a lot of personal settings were still there.

I recommend you take a backup of the most important stuff - the stuff you can't afford to lose, and then do a repair install. It took my system about 2.5 - 3hrs to complete (it has to copy all your files and apps).

Here's a very good guide on how to do it, what to expect, and how to clean up afterwards.

Repair Install

If your OS is doing something it shouldn't be doing, a repair install will almost certainly correct this (unless you have another app installed which has altered things).
