I had previously been using a pair of Aquantia AQC107 (Marvell/AQtion) Tb3 to 10Gb Ethernet adapters to connect my NUC8's together. It was working fine, but I upgraded to NUC10 and can't get them to recognize the device at all.
I have updated the BIOS to latest available at this time (0037) and tried resetting all settings. Windows 10 tried 1709, 1809, and 1909 versions, updated TB3 software/drivers from Intel's site as well as ran DSA Driver Support Assistant and updated everything.
In Device Manager > System Devices I do see a "Thunderbolt(TM) Controller - 15E8" device and it says it's working properly.
But, when I connect the device to the rear TB3 port, nothing happens. No dialog pops up, nothing happens in Device Manager, etc. It's like the device is "dead". Plugging it into my Mac works fine.

There was no known fix. I powered the NUC off and let it sit for a little while, a few OS reinstalls later (switching between Debian Linux and Windows 10) and it just started working. No idea why. I think there's a BIOS issue - this being a new model I am sure there are bugs to be worked out.
