Welcome to Lenovo Community Forums!
Can you share the Device ID of your Ethernet controller and that Unknown Device.
Open Device Manager and
Under Device Manager
Right-click on your Unknown Device and choose Properties
Then like on the photo
click Details Tab
click on the dropdown and Choose Hardware Ids
Then Copy the first line of the hardware ID
Let me know your findings
