First my full system details can be viewed below under My Computers
In summary a new Intel i9 13900K based PC with a Asus ProArt Z790 Creator Wifi mainboard with the latest bios.

The issue is that all devices in the Device manager have drivers apart from one unknown device as per this screenshot.

The hardware ID's are:
ACPI\VEN_INT&DEV_3515
ACPI\INT3515
*INT3515

There are other similar devices already installed. Here is one of them.

Does anyone know what driver I need? I have tried several drivers and done a lot of searching online but have come up with no solution.

Thanks for you post. (y)


That thread you pointed me to at the ROG Forum solved the issue.
It is the Thunderbolt drivers (Texas Instruments).
Solved the issue by installing the Thunderbolt drivers from the Asus ProArt Z790 motherboard website.

It now shows up in the Device Manager under system devices as per this screenshot.
