- Does Thunderbolt appear in the Windows Device Manager?
- If you have a Thunderbolt device, what happens when you plug it in? Does that device appear in Device Manager?
- You may also download and run HWINFO64 on Windows, then save the output in .HTM format and upload.
First, I read somewhere that if I have an NVMe in the lowest slot, it shares system resources with the lowest PCIe slot. I removed it and now have internet in both TB ports, in Windows. The AIC now appears in BIOS.
No to device manager although I am thoroughly ignorant about Windows so it could be there and I would not know it.
HWINFO64?
Restarted into Mojave. I have Internet through the TB>Ethernet dongle. I have a USBc flash drive that appears in Windows but not in Mojave through the AIC. The AIC is not showing in System Info in Mojave.
