I been using Thunderbolt NIC on my Crosshair X670E Hero for some time without any issues but recently I updated the BIOS to 2007 (I don't recall what I was running on before) and noticed that my Thunderbolt devices connected, upon reboot, would disappear. They still show up under Thunderbolt Control Center, but just completely missing in Windows Device Manager. The only way to reset this is to unplug and plug them back in, which is very annoying. Is anyone else experiencing the same issue or know what the fix would be?
