+  The special "WII" pin means that the device will use the host's Bluetooth
+  address to compute the pin code as explained at:
+  http://wiibrew.org/wiki/Wiimote#Sync_Button

   If a device can use a random PIN but is limited in the number of digits that
   can be entered, then set the "pin" attribute should be set to "max:X" where X
   is the maximum number of digits, for example max:4 for 4 digits.
