That is not any more right than saying that interrupts reside in
/proc/interrupts. The /proc/bus/usb tree is only an informational way of
showing you what usb devices are present, they are not the actual "device"
files. Those still reside in /dev/*usb* or /dev/usb/* (depending on whether
you use devfs or not).
