Hi,

some time ago a new version of the joystick configuration file for Logitech Wingman FF 3D was committed, containing a change to the throttle-handling.

Shortly after that I couldn't get the engines down to idle. As I noticed, jsdemo reports that the throttle axis returns +0.3 when on idle. I'm using Linux on a 2.6.8 kernel.

I thought that plib would calibrate the joystick axes to 0 in the positions they are in on construction of the plib Joystick object. However, there is no evidence on this in the plib code.

I had to go back to a previous version of the configuration file and idling worked again.

Maybe we should have a general calibration utility and load the resulting data on FlightGear startup. This would also spare us some of the offset-hacks in joystick configuration files. I don't have time right now (maybe within a week's time), but if nobody else jumps in I'll create a tool as soon as I have time.

Best regards,
Ralf
