I've just upgraded my MOBO from ASUS Z97-AR to ASUS Z97-A USB3.1. Everything works fine, as this is basically the same motherboard, however, I am not able to configure and use my ThunderboltEX II card properly.
The thunderbolt card worked flawlessly with my old MOBO, but it is not functioning properly with the new one. I can see the card in the BIOS, but it is not working in Windows 10 64bit.
I have reinstalled all the related drivers, still no success.
When I try to upgrade the ThunderboltEX II firmware, it says this.
Forcing power to the Thunderbolt controller(s)... The Thunderbolt controller(s) is now powered. Failed to load Thunderbolt(TM) controllers through WMI.
Please click the "Cancel" button to finish the tool.
Any idea?
