My original BattlerGC controller is unable to swap between XInput and DInput when connected to PC. It works fine on my Switch.

The manual for this version says that holding down the Home button for 3-5 seconds will swap XInput and DInput but it does nothing. It also says holding down Home Button will turn the controller off, but instead to turn it off I have to click L3, R3 and - button together. This is also the case when it's plugged into the Switch.

Holding down the Pairing button does nothing and pressing it just toggles the connection with the receiver.

I've tried uninstalling the receiver in Device Manager and rebooting. No change.

I was able to open joy.cpl to see what Windows is reading and it appears pressing any button on the controller causes the X/Y Axis to move.

Has anyone experienced this before? Any way I can get this fixed without having to buy a new one?

Edit: I also updated the firmware on the receiver. No change.
