Can I Bump this thing to make it more visible?

1. Passthrough of PCIe USB expansion cards. I was following SpaceInavderOne's video on how to passthrough a USB device and once I reset my PC the USB controller didn't show up in the VM editor. What I noticed after re-checking if i followed the steps correctly is that even though my 2 PCI-e expansion cards come from different vendors they appear to be using the exact same controller. The controllers are both in their own IOMMU groups but they have the same ID. What can I do ? IOMMU group 19: [1106:3483] @.0 USB controller: VIA Technologies, Inc. VL805 USB 3.0 Host Controller (rev 01) IOMMU group 21: [1106:3483] @.0 USB controller: VIA Technologies, Inc. VL805 USB 3.0 Host Controller (rev 01) 2. At the same time I was messing around with my VM (it's set up in a way that I can dual boot into VM or directly into Windows) - When I did this setup i checked that the normal boot still works, but now, after about a year when I tried to boot straight into Windows it didn't work - windows logo shows up and that circle of dots keeps spinning - sometimes it freezes. After a few hours I said F*** it and tried booting into the VM again. It started normally but I was limited to some 4:3 resolution. After some more messing about, trying to figure stuff out, I got to 800x600 resolution. Next day I didn't even get a video output when I chose to passthrough my GPU (it was a quadro 2000) - Not only there is no video output, the windows doesn't boot. But if I remove the GPU and use VNC the VM works normally... Now I tried the 2000 in my other VM which has a GTX 1070 and it didn't work, so I thought maybe it's the GPU... I got a quadro 4000 ... still doesn't work in the first VM. Then I tried booting into my other VM with the 4000 ... Works but not perfectly - Change back to 1070. I was again limited to 800x600... This time I started thinking that this resolution problem must be a driver problem so I went to device manager and uninstalled the video driver for the 1070. Restarted and everything works perfectly. So this got me thinking that the first VM also might have a driver problem that is keeping me from booting into windows with a GPU passthrough, but the thing is that the driver doesn't show up in the device manager when I use VNC. So how can I find the right driver to delete? By going to c:/windows/system32/drivers ? by going to regedit? Do you think it might be something else ? P.S. I was reading a thread on this forum about passingthrough where they said to try running the VM with Hyper-V set to OFF, but when I set it on OFF , update the setup and go back to edit the VM the Hyper-V is set back to ON.
