# By default, vboxdrv creates a file /etc/udev/rules.d/60-vboxdrv.rules every time, it is started, 
# that allows full control of this hosts usb devices in virtual machines (given, you allow accessing
# them with the GUI).
# In order to control this ability yourself, copy the generated /etc/udev/rules.d/60-vboxdrv.rules
# file to another name and modify to your needs, e.g. comment out all lines beginning with SUBSYSTEM,
# which will make this hosts usb devices inaccessible AND enable the next line.
