UnoJoy won't show up on PC

Hi,

I recently programmed my Arduino UNO (not a clone) into an UnoJoy Joystick as per this set of instructions:

https://code.google.com/archive/p/unojoy/wikis/GettingStarted.wiki

It worked, and I tested it several times.

The other day I soldered some components from a flight simulator yoke to some pin headers, and put them in the Arduino. When I went to test the controller, the computer now no longer recognised a device being connected:

  • There is now no "du-dink" sound when I connect the cable
  • The device does not show up in Device Manager or Devices and Printers
  • The power and pin 13 LEDs light up, and different cables have been tried
  • The Arduino does not show up in the IDE either

Does anyone have any idea what I have done to it, and/or how I can fix it?

Thanks in advance,

Jonathan
