How can i modify the HID descriptor that is installed in windows when the Leonardo is detected as USB device ?
I need to create a force feedback capable device with arduino, but all the force feedback part is missing for now.
I have found this one :
https://code.google.com/p/sidewinder-arduino/source/browse/#svn%2Ftrunk
But i don't know how to make it work 
I have also find that too add forcefeedback ( rumble ) to a dualshock joypad the installer add to the register this keys :
