You may want to try the drivers from these forums, they are more current than the drivers on the Asus site:
I have a Prime Z690-A with the ThunderboltEX4 expansion card and a UAD Apollo Twin MK2 that is working fine. The TB Control Center app is not available for Win11, and it was flakey on my old Win10 system, so you may want to just ignore that app. Not sure if the settings are the same on your board, but these are my BIOS settings (pulling from a config backup file so not sure if this is everything):
PCIE Tunneling over USB4 [Enabled]
Discrete Thunderbolt(TM) Support [Enabled]
Wake From Thunderbolt(TM) Devices [None]
DTBT Go2Sx Command [Enabled]
Windows 10 Thunderbolt support [Enable + RTD3]
DTBT Controller 0 [Enabled]
TBT Host Router [Two port]
If the newer drivers don't work, you may want to check the following thread and support article for some other options (different TB hardware but the solutions may be the same):
Hope this helps!
i had same problem. problem is thunderbolt controller.
don't need touch bios setting.
and you have to find "thunderbolt(TM) controller -1137" in windows control panel ->device manager->system device
it is defualt. even if UAD is working or not.
and trust thunderbolt control center APP.
in APP you have to find port1, port2 line,
and if you install thunderbolt driver you can always find in APP's information tap, thunderbolt software, PCIe tunneling - enable
you have to find these, it is default.
if you can't find these, your mobo's problem. thunderbolt controller is dead
i change my mobo,(same proart Z690) and working great.
but always turn on uad first, and booting computer.
i think thunderbolt controller is weak. when i using macbook, sometimes it was faint, or make short.
