I am not able calibrate USB joystick TRUST PREDATOR TH 400
I run jstest /dev/input/js0
Axes 0 minimum - center: -1 ... -114
Axes 0 center- maximum: -114 ... -127 ... 127 ... 34
Axes 1 minimum - center: -31 ... -127 ... 127 ... 118
Axes 1 center - maximum: 118 ... 10
Low level positions are negatives, high level positions are positives. Center position go from value -127 to value 127. jscalibrator is confused. I am not able calibrate joystick.
