   Okay, will do so...also, is itme who has an outdated version of=20
input.h, or does it really not have ET Ramp, Damper, and Inertia?? And=20
what would FF_RUMBLE be?? Is it I-force specific?? If it's okay, I'll=20
add FF_RAMP, FF_DAMPER, and FF_INERTIA since they're defined in the=20
spec(5.1.1)...

   Yes, I know...have you decided how we'll do that?? I guess that=20
since(in PID specs at least) custom effect data is sent on one(or more)=20
report by itself, saved in a memory position(just like an effect), etc.,=20
we could just make an IOCTL to upload the custom data, then we can=20
normally upload an effect which points to that custom data...that would=20
require only minor changes to the existing code...

P.S.: I've started libff too...send me all ideas you have for nice=20
things it could do...I'm using re-usable parameter blocks(something like=20
FF_create_constant(float direction, float magnitude, FF_envelope=20
*envelope, FF_trigger *trigger, FF_time *time, FF_flags flags)  )

--=20
