[ovirt-users] USB Passtrough device problem

Hi, I've tried to use 2 different audio IO interfaces connected to a VM via USB passthrough and none worked. I've tried with win 10 and win server 2016 vms with different errors but none worked. I've connected the devices to a host, then attached the host device to a VM and in the VM properties I've enabled the USB support in the console properties. The devices are installed and don't show any error in the device manager within the VM, but they don't work. Should I do something else? Regards
