PCI-E Passthrough issues with USB Controller

[StevenRafferty]

Hello,

 

I am having some trouble with my USB controller, I have three devices connected to it: Gaming Headset (Astro A50), keyboard and mouse, when I use the headset my mouse or keyboard will get disconnected, I am open to any suggestions.

 

The solution I am using for now is to only have the headset on the USB Controller and keyboard and mouse on Motherboard USB and passed through via VM.

 

I am not sure if this is worth mentioning but when I tried running the VM with USB Controller option set to 2.0 it would just stay on the windows loading screen.

 

System specs:

CPU: i9 9900K

GPU: RTX 3080 ti

Storage: 3x 1TB SSD

 

Here is my VM XML
