Question Asus ThunderboltEx 3 in Asus Prime Z-270-A

[martel80]

Hello,

I really need help here. I dont understand what Im doing wrong.

I just bought an Asus ThunderboltEx 3 to get my Focusrite Clarett 8preX to be installed on my Windows 10 (Build 19041.509) on Asus Prime Z270-A.

I first installed my Asus ThunderboltEx 3 on my PCIEX_3 slot and connected it to the TB Header just on top.

I then went into the BIOS and made those change to the advance menu - Thunderbolt submenu

I then went on the Asus website and instlled the First utilitie on the ASUS website which didnt got my ThunderboltEx 3 to appear on the device manager under System Devices.

So I proceeded to install the 2 other one I found on ASUS website which didnt seem to install anything anyways.

I must say that at this point Im completely clueless as theres little to no documentation as to how to correctly install that ( what should be a plug and play ) device .

Can anyone give me a hand on what I missed .

Did I made a mistake in the BIOS ?

Can someone guide me or post a step by step .

I have no clue as to what to look at.

Thank you very much for your help.
