This issue has been present every since I bought Tartarus Pro.
I use my Tartarus and mouse for most PC games, but for some I use my XBox controller.
For some games, the contoller does not work, unless I unplug the Tartarus.
Some games it works fine.
I have contacted Razer support about this many times and it has never been fixed.
Has anyone else come across this behavior and found a way to fix it?
