I have a box which is running Server 2008 R2 for development purposes.
I have swapped out an ASUS M3NH-HDMI setup, for a Gigabyte F2A85X-D3H series (inc CPU, RAM, etc).
As the new board has UEFI & USB 3.0, although the swapover worked like a charm, some USB ports are non-operational (most likely the USB 3.0 ones) and the Realtek PCI-E onboard card is coming up as: This device cannot start. (Code 10).

I have disabled Legacy USB support in the BIOS and am still working out the XHCI and EHCI Hand-Off settings.

For effectively what is identical to Windows 7 x64 setup, what should the XHCI & EHCI settings be set to to enable the ports and resolve the driver issues?
Driver fault
I've tried both enabled & both disabled but with no luck.

Legacy USB Support Allows USB keyboard/mouse to be used in MS-DOS.
(Default: Enabled)

XHCI Hand-off:
Determines whether to enable XHCI Hand-off feature for an operating system without XHCI Hand-off support.
(Default: Enabled)

EHCI Hand-off:
Determines whether to enable EHCI Hand-off feature for an operating system without EHCI Hand-off support.
(Default: Disabled)

Legacy USB support is off.

A couple of pages said that the Realtek driver issue may be caused due to the USB port driver issues.

Any ideas?
