Why not do a patch for VirtualBox to make it look in the right place
first ? We've just done that for QEMU too, changing its search order
to be /sys/bus/usb, /dev/bus/usb and only then /proc/bus/usb. Removing
the whole /proc/bus/usb mount to solve one application's problem does
not seem ideal.

FYI the distinction VirtualBox vs libvirt isn't correct. libvirt is
an API for any virtualization technology, and has drivers for Xen,
KVM, QEMU, VirtualBox and more.
