--- Comment #1 from Bruno Jesus 00cpxxx@gmail.com --- Did you pass the "--force-feedback" parameter when starting xboxdrv? As far as I remember without that parameter it will not enable FF.
Please attach a +dinput log, read more about how to get that at https://wiki.winehq.org/FAQ#get_log
The log will help checking if the kernel is delivering the input as triggers or buttons. The problem is only for the triggers?
