That's why I moved the discussion to linuxconsole-dev, this is an input 
layer problem, not a USB problem (hopefully Linus will move that stuff over 
to drivers/input before 2.4). It will probably get assigned the same USB 
ID, but if the application still holds eg. /dev/input/js0 open, it will now 
be assigned to /dev/input/js1 :-(. And the application won't notice at all.

Heh, then move the input drivers from drivers/usb to drivers/input where 
they belong. With a README file somewhere, the probability that 
bugs/problems will get reported to the right list should be somewhat higher 
:-).
