as long as the devices created in between are also punted, this should be 
fine.  i was thinking of this case as you dont want:
 - usb start
 - probe some usb net devices (get usbnet0 and usbnet1)
 - usb start
 - previous usbnet0/usbnet1 still exist, and the counter has been reset to 0 
so the new devices start back at usbnet0

if there's something in the bigger picture that takes care of this already, 
then this is probably fine.
