File exists in that folder also on my system: # cat /usr/lib/udev/rules.d/60-vboxdrv.rules KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="vboxusers", MODE="0660" KERNEL=="vboxdrvu", NAME="vboxdrvu", OWNER="root", GROUP="vboxusers", MODE="0660" KERNEL=="vboxnetctl", NAME="vboxnetctl", OWNER="root", GROUP="vboxusers", MODE="0660" #SUBSYSTEM=="usb_device", ACTION=="add", RUN+="/usr/lib/virtualbox/VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass}" #SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", RUN+="/usr/lib/virtualbox/VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass}" #SUBSYSTEM=="usb_device", ACTION=="remove", RUN+="/usr/lib/virtualbox/VBoxCreateUSBNode.sh --remove $major $minor" #SUBSYSTEM=="usb", ACTION=="remove", ENV{DEVTYPE}=="usb_device", RUN+="/usr/lib/virtualbox/VBoxCreateUSBNode.sh --remove $major $minor" But, the popup, which asks, if I want to have the USB Passthrough enabled or disbaled is occuring for every start of VirtualBox. Is this the expected behavior?
