The LED setup in this case is done entirely manually by me writing to the 
individual files in /sys/class/leds/. This has to be done when the controllers 
are connected initially, and if a controller has to be reconnected for some 
reason (e.g. it runs out of batteries). I don't know of any userspace tools 
that would make this easier to automate, except maybe a shell script, and I'd 
probably still need to run it manually.

Both the Sixaxis and Xpad drivers appear to implement something similar, so 
perhaps a higher-level "player number" mechanism that works with all 
controllers would be worth looking into. This could in theory be done with a 
userspace daemon too (or a udev hook).

As it is right now, I still think implementing it in the wiimote driver is the 
best method to keep it consistent with the rest of the drivers without having 
to install additional userspace tools.

Thanks
