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)?
