Guys,
I have a strange occurrence.

I have a Teensy 2.0

1. I connect it the first time through USB, it starts flashing but doesn't appear in the Device Manager as something obvious nor the Driver Updates automatically and when I find the actual profile on the Device Manager and update the driver it is already updated.
2. I open MMJoy2.exe and upload the firmware, it says COM1 despite not being COM1
3. When restarted the Teensy it appears in MMJoy2.exe as VID:8888 PID:8888 MMJoy2 (MMJoy2-20151118)
4. I go to Joystick Buttons and put B2 and B3 as matrix columns as I have a single button connected to those for testing.
5. The button number 1 turns red when I press it.
6. The MMJoy2 appears as Game Controller in the Devices and Printers. However there is no calibration or anything like that.
7. I start War Thunder and try to set up Engine On by pressing the button.
8. Nothing happens.

Am I missing something? Even if I close MMJoy2.exe and disconnect and reconnect the Teensy War Thunder doesn't recognize the buttons.
Do I have to set up in normal working mode?
