On Designare Z390 and Z490 Vision D, the new BIOS kills USB on the built-in Thunderbolt ports. I haven’t checked the behavior of an add-in Thunderbolt card under these circumstances.
ASUS is in contact with me regarding this, I am about to send them some materials and explanation so they can fix this.
I suggest if you guys have time to email them at:
They have fixed some BIOS issues before when I emailed them. Especially if this issue is across multiple motherboards, they will for sure fix it.
