I suppose you just want to make usb.usermap an empty file. But anyway, 
even if you do that, in the cold-plugging scenario with modular USB 
drivers your script will be called twice (once for the synthetic hotplug 
event and once for the real one), so you just have to be prepared to see 
duplicates.
