Win 7 Ultimate and Ubuntu 14 Dual boot... USB ports do not function when booting to Windows after Running Ubuntu

[Dagger61]

USB ports do not work in windows 7 after dual boot install of ubuntu 14. Rebooted into Windows 7 install disk and performed start-up repair. After that, the USB ports work in Windows. HOWEVER, after booting to the Ubuntu partition and working there, I shut down the machine and boot to Windows and the USB's are dead again... Any ideas?

I'm also having this problem but I'm on Windows 8. It's really frustrating me and I can't find a solution for it as uninstalling and reinstalling drivers aren't helping.
