Ah, nice to hear. I had some additional questions that might benefit to the porting of the lgff and sony driver, concerning the optimal value for FF_UPDATE_RATE (at the moment it defaults to a safe 50ms): - Could you try to sniff FF command USB traffic with the Windows driver of the WingMan Force, just to learn what the update interval is when playing a ConstantForce effect with an envelope (I'm only interested in the envelope part)? - If official/decent Windows drivers are present for one of the Sony controllers you have, can you please do the same, but now when playing a vibration effect (using XInput)?
