This command worked. I was able to pass through the usb and also pcie devices i can get to using XO.

windows host showing usb drive plugged into usb3 card and graphics card.

Perfect! It's just a matter of stuff hidden for some reasons, at least it doesn't cause any problem, which is what matters

is there anyway to block igpu from being used by xcp-ng during boot? I have it setup for pass through but it fails under the VM. I think it because xcp-ng still displaying the console screen and does not want to give it up.

so it seems like when i make the igpu pass through, i see the starting lines of xcp-ng but it never gets to the console screen. which is what i expect.
When I add the pcie devices (igpu/hdmi audio) to a vm and start it up, I get and update to the screen and it shows a red number counting which is part of the console.
So it seems that when the VM re-initializes the igpu, dom/xcp retakes it over.
I confirmed that by using the keyboard to move around and it reshowing the console and filling the missing details as i move around.
So why is the dom/xcp retaking the video device over again when it should be blocked from accessing it?
