Hi all,

since yesterday I am not able to use any USB device via my Thunderbolt card anymore.

System:
X570 Steel Legend with now BIOS 3.0
Thunderbolt 3 AIC R2.0
Elgato TB 3.0 HUB
Nvidia 2080 connected via Elgato

So the Displayport on the Thunderbolt 3 AIC R2.0 works still fine, but all USB devices does not work anymore. So I tried to connect an USB3.0 HUB directly to the second TB port of the Thunderbolt 3 AIC R2.0 also I tried to connect my mobile phone directly to this port does not work either.

So I removed the Thunderbold driver - no success
I updated the BIOS of the steel legend to 3.0 - no success
Checked if any driver update/ windows updates have been apllied - nope, no driver updates

All other USB Ports on the Steel Legend works fine. How can I check if this is
a software/driver issue or if the TB 3 AIC R2.0 is causing the issue?

Regards,
Dirk

Ok, I found the issue. All Bios settings have been deleted and set back to default. However that could happen.
