In addition to the blacklist methods you've been given, there's also the pci_stub driver which can be used after the distro is booted. This is advantageous in that you can kick out only one of two identical devices without having to block/unload the entire driver. The procedure is something like this: # echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id # echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind # echo 0000:01:00.0 > /sys/bus/pci/drivers/pci-stub/bind This is typically the method used for PCI pass-through to VM's. I don't know how to do this for USB but I'm pretty sure there's a way to do it as there's a UI for it exposed in libvirt-gui. -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
