The VirtualBox developers state:

"/proc/bus/usb is deprecated, and most people have already got rid of

this to avoid breaking existing working setups. Otherwise we use newer,
alternative code."

My analogy was poor, yes, as most Internet comments are, but my point
was being VB vs what libvirt provides, not what libvirt is (a library).
