Just to give an update on this, I was having issues as I use both a Tartarus as well as an Xbox pad from time to time and the unbind method makes this a massive pain due to unbinding all of the keys. I have however found a workaround that should allow BOTH the Tartarus and a game controller to work interchangeably without the need to unbind or unplug.
The Tartarus' thumbpad is what causes the issues here as windows detects it as an analogue stick at all times which can then trigger some games to think that a controller is connected and prevent certain actions or trigger controller ui.
To disable this analogue stick behaviour, you need to:
- Go to Device Manager
- Under Human Interface Devices, find HID-compliant game controller
- Right click the device and select Disable device
(If you have multiple of the "HID-compliant game controller", to find the right one, simply right click and view the device properties, go to the Events tab and at the very bottom you should see Parent Device: RZVIRTUAL)
This should remove the analogue function from the Tartarus and allow you to use either a game controller or the keypad independently. The main drawback to this approach is that obviously it takes away the analogue part of your keypad's functionality but it does allow the thumbpad to be used in the d-pad mode.
