Oh, and I forgot some other things that need to be mentioned: - Trigger-button is not yet implemented, as far as I know - Custom force effects, in Linux it is called FF_CUSTOM. (however I think we can neglect this effect for now) - Infinite iterations in the Linux FF API is not supported.
@Roland: Now I understand why Logitech Windows drivers have bugs in the periodic implementation of the DInput specs: Logitech seems to have based their drivers on the Immersion Studio visualisation of the to-be-generated periodic effects, and these visualisations are not conform with the DInput specs of MSDN. Take a quick look at the MSDN specs for e.g. SawtoothUp: http://msdn.microsoft.com/en-us/library/windows/desktop/ee418719%28v=vs.85%29.aspx Now open the Immersion Studio (demo) and create a standard SawtoothUp effect, and look at the visualisation... It's wrong, right? Same applies for SawtoothDown and Triangle.
