Currently, unraid requires all USB devices added to a VM to be present on startup of that VM, or the startup fails. Libvirt actually supports adding USB devices as optional for VM startup using hostdev startuppolicy, see details below. But this can only be done in the XML view. It would be great if we could have another checkbox in the form view to specify that we want a specific USB device to be included with startuppolicy = optional. This will reduce the need to edit the XML directly
