Just noticed both of my USB sound devices I used disappeared at some point during the jittering. Meaning I now have to reboot to try and get my USB working again. This seems extremely tedious with now way to PnP USB devices. I'm assuming I'm not the only one with these issues?

I got Unraid installed/my gaming PC setup with passthrough after a long 10 hours yesterday....and so far the experience has been middling. While I was able to test a game without issue, and overall the VM passthrough setup seems basically unnoticeable, there are some game breaking negatives for me: After PC was locked all night(sleep completely disabled), my keyboard wasn't working this morning. So I had to restart the VM which didn't fix it. Then I had to go edit the settings and hit save, then edit the XML manually to fix passthrough for the GPU and save. And then upon booting it worked again. This seems like a very manual and arduous process to go through every morning if my USB keyboard just can't keep working, and there is no way to plug and play it to fix. Is the solution to get a USB-C hub that I pass through and then everything else plugged in to it might be PnP as part of that? While typing this my mouse just went very wonky and moves across my screen much slower/seems jittery. Keyboard seems to be lagging as well. So it seems like there are random bottlenecks for USB passthrough? It just came and went as I typed this out. It seems some of my docker apps might have been doing something and spike the 6 cores I have reserved for them to 25% usage. If that is all it takes to cause a noticeable impact that also might be a deal breaker for me. If this setup works I am planning on upgrading from my 3900xt(possibly the problem?) to a 7950x this weekend. Does anyone else run this as their daily setup? I work from home so my Gaming PC is generally my main PC. In the future I would like to get another GPU possibly so I can run dual VM's and segregate my machines. I just want to prove out it is stable and performant enough before I make the investment on a huge upgrade. Any feedback and/or recommendations are appreciated.

I think I'm close, but possibly not modifying something correctly. The first problem is when I boot unraid it still tries to use the onboard GPU and I get output while booting. So I'm unsure how to disable that. Currently my bios is set to CSM mode(I read that helps), but that only changed it from outputting in native 4k to lower res. Second, I think I'm not setting the multifunction thing and IOMMU group correctly. Here is what my IOMMU config looks like for my 3090(I have the 2 devices selected and clicked the "Bind selected to VFIO at boot" and restarted): So with that I go in to my VM settings and update the following(before modification): <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x2d' slot='0x00' function='0x0'/> </source> <rom file='/mnt/disk1/isos/GA102.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x2d' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> to: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x2d' slot='0x00' function='0x0'/> </source> <rom file='/mnt/disk1/isos/GA102.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x2d' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x1'/> </hostdev> But after that change it still doesn't work. Note: I only change the slot from 0x06 to 0x05 to match the GPU. Before all of this I installed the OS via VNC mode, and then at one point on a reboot it actually booted in to windows since I installed the OS directly on one of my NVME's, so I took that opportunity to install GPUZ and dump my vbios. I also tried using a downloaded vbios and removing the needed section....but I can't tell if I did it correctly/that didn't work either. So to recap: How to I edit my unraid config to disable it from using the GPU on boot up if that is an issue? Am I editing my xml incorrectly above? Did I hurt something by letting the the VM boot directly from the PC outside of KVM?
