Cannot use USB 2.0 device in Front Panel USB 3.0 port after Windows Update

Hi,
Motherboard: Asus P8Z77I Deluxe

When I install my old Win 7 Pro OEM disk and then install drivers off the Asus cd, my front panel USB 3.0 ports work great with both USB 2.0 & 3.0 devices.

After installing several updates including SP1 USB 2.0 devices are no longer recognized but 3.0 is fine. I then installed the latest drivers I could find but no joy. Any help here?

Thanks,
CxP
