 Alternatively you can also restart your PC or use another USB PID (in the boards.txt) to see if its a Windows problem or not.

 Gamepads had several problems over the time. The first thing I'd like to mention is that the calibration windows only updates if you focus it.
 Windows only supports gamepads with up to 7 axis and 32 buttons and has problems with more than one Gamepad in a multireport.
 Linux has problems when gamepads are in multi reports with a system device for example. It may occur that it display immense axis/buttons or none at all.
