OK, this isn't FG xml issue. js_demo reports correct (-1.0 <-> 1.0 etc.) But as soon as I either start js_demo or fgfs, when I check joystick in KDE or use the jstest utilty, X Y Z at rest are set to '337'. So something recalibrates the stick to that. This is what I meant about the deadband stuff from plib: plib-1.8.4/src/js/jsLinux.cxx [sic] // Remove any deadband value already done in the kernel. // Since we have our own deadband management this is save to do so. So I am wondered if kernel sets up the joystick correctly - then plib decides the deadband is wrong and changes/removes it somewhat. I don't know.
