Q35 - Yellow Exclamation marks on Passed through devices

[mikeyosm]

Hi

 

On devices that are passed through to my W10 VM they both have yellow exclamation marks (error code 10). In ifx they did not have this.

 

0x71 is my USB controller, 0x1b is my onboard realtek sound.

 

Any ideas why this might be? Here is my XML.
