I do not understand if it's a problem of my gpx or something wrong in GPB, but my gamepad calibration not works well now (probably since I installed the beta 9c) ???
Here a little vid that shows the problem:

The GPX pad is seen by Windows exactly like an Xbox360 controller.
This means that you can use the XInput interface and calibration is not only not needed, but also discouraged.
Ah ok, thx for the info ;)
