I don't think that's quite right - but there's no one who wants to
reintroduce /proc/bus/usb/devices to support applications using obsolete
methods. It's not the only one, however, as the VirtualBox non-ose version
needs it too.
fwiw, you need this in /etc/init.d/mountdevsubfs.sh (googling "usb
virtualbox ubuntu" should bring up lots of examples).
# Magic to make /proc/bus/usb work
[ -d /dev/bus/usb/.usbfs ] || mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0666
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb
