April 1, 20206 yr I recently purchased a Rosewill 4-port USB 3.0 PCI Express card to give some usb hot plug support to one of the VM's I'm running from my PC. The device seems to work and if I plug in a usb device, it shows up in the unraid System Devices List. I can successfully pass through the device to a virtual machine with nothing plugged into it but as soon as I plug in a usb device the entire system locks up and I have to Force Stop the VM. If I try to boot into the VM with a device plugged in then it just hangs on the TianoCore loading screen before windows 10 gets a chance to boot. I have PCIe ACS Override enabled for reference. I've already added the device to the append list for unraid on boot. Quote kernel /bzimage append vfio-pci.ids=058f:6364,07fd:0002,8086:a370,8087:0aaa,046d:082d,041e:3249,1a2c:4324,1912:0014 append pcie_acs_override=downstream,multifunction initrd=/bzroot,/bzroot-gui
