    Using Teensy 3.1 as joystick, not showing up as game controller

    I've recently migrated from a Teensy 3.0 to a Teensy 3.1 board. I had written a sketch for the Teensy 3.0 board that obtains data from a Wii Nunchuk using I2C (communicating via pins 18 & 19, with pullup resistors to 3.3V). Below is the basic outline of my sketch:

    Code:
    #include <i2c_t3.h>
    
    #define NUNCHUCK_ADDRESS 0x52
    
    uint led_count;
        
    void setup()
    {
      pinMode(13, OUTPUT);
      pinMode(14, OUTPUT);
      led_count = 0;
      Joystick.useManualSend(true);
      Wire.begin();
      SendByte(0x55, 0xF0);
      SendByte(0x00, 0xFB);
      
    }
    
    void loop()
    {
      int count = 0;
      int values[6];
    
      Wire.requestFrom(NUNCHUCK_ADDRESS, 6);
    
      while(Wire.available())
      {
        values[count] = Wire.read();
        count++;
      }
    
      ... More Code here to process the data from the device ...
        
      Joystick.sliderLeft(analogX+512);
      Joystick.Zrotate(analogX+512);
      Joystick.sliderRight(analogY+512);
      Joystick.X(accelX);          
      Joystick.Y(accelY);           
      Joystick.Z(accelZ);
      Joystick.button(1, zButton);
      Joystick.button(2, cButton);
      Joystick.hat(hatAngle);
      Joystick.send_now();
        
      SendByte(0x00, 0x00);
        
      if (zButton > 0 || cButton > 0)
        digitalWrite(14,HIGH);
      else
        digitalWrite(14,LOW);
      
      if (led_count < 20)
        digitalWrite(13,HIGH);
      else
      {
         digitalWrite(13,LOW);
         if (led_count > 30)
           led_count = 0;
      }
      
      led_count++;
      delay(10);
    }
    
    void SendByte(byte data, byte location)
    {
      Wire.beginTransmission(NUNCHUCK_ADDRESS);
      Wire.write(location);
      Wire.write(data);
      if ( Wire.endTransmission() > 0)
      {
        //Do something
      }
    }
    After resolving a compilation error that was occurring from the included i2c_t3 library (from help on this thread), I uploaded the sketch to my Teeny 3.1 (after choosing "Serial/Keyboard/Mouse/Joystick" in Tools>>USB Type in the Arduino environment). However, when I opened the Windows Game Controllers Control Panel (joy.cpl), the device was not showing up.

    Unsure if there was a hardware or software problem, I connected the board in parallel with the Teensy 3.0 board (with the clock and data wires connected to both the Teensy 3.0 and 3.1 boards). I then uploaded the same sketch to each. The Teensy 3.0 board showed up in the Game Controllers Control Panel and was receiving/processing the data correctly, the Teensy 3.1 did not even show up.

    I tried reinstalling the Arduino environment, as well as the Teensyduino uploader.

    Any thoughts on what I'm doing wrong? Am I missing a driver of some kind for the Teensy 3.1?

    I also just tried sending the data over USB via Serial, replacing the Joystick code with Serial prints:

    Code:
        Serial.print(analogX, DEC);
        Serial.print(' ');
        Serial.print(analogY, DEC);
        Serial.print(' ');
        Serial.print(accelX, DEC);
        Serial.print(' ');
        Serial.print(accelY, DEC);
        Serial.print(' ');
        Serial.print(accelZ, DEC);
        Serial.print(' ');
        Serial.print(zButton, DEC);
        Serial.print(' ');
        Serial.print(cButton, DEC);
        Serial.print(' ');
        Serial.println(hatAngle, DEC);
    I then selected "Serial" in Tools>>USB Type.

    When I did that, compiled, uploaded, and then opened the Serial monitor, I could see that the data was being sent correctly.

    Possible Solution

    I am having the same problem, joystick not showing up as game controller
    On my Windows 7 development machine. On another Windows 7 PC the Teensy 3.1 is working as expected.

    This thread might help

    Short version of fix
    --------------------
    Delete from the registry all keys containing VID_16c0.

    I have not deleted the keys yet so I cant confirm it will work.

    I had the precise same issue, and i can confirm that deleting all occurrences of VID_16c0 in registry fixed it
