Stabel ids on Identical devices on the event input subsyste

Hi guys 

If I have several identical joystick connected, with the old /dev/input/js* system, they would appear in the same order (if they were initialized in the same order).. but on the event system, they most times are not.. (probably because other event devices are initialized in between).. 

Is there anyway to solve this??
