Not exactly periodic, but same effect may be achieved using periodic effect with 0 period. This constant effect sets constant motor speed (and also could be more powerful, than periodic). Periodic effects control motor speed using effect type and parameters, so speed amplitude graph is sinusoidal or saw-like. Envelope for constant effect controls effect playback begin and end. For periodic effects it controls every period, as I understood. >> I tried this, no result. >> I think, this problem is connected somehow to log message about >> maxusage and report_count do not match. > > It is not related to those.
