Tartarus Pro Detection Problem

So I picked up a Tartarus Pro from amazon after seeing the option for a keypad with analog input, this is great because I love having a mouse for aim but in more immersive games I like the option of moving with analog fluidity. After getting it set up I've run into an issue. Despite the customization options, by default the keypad gets detected as a gamepad/controller. This is a big problem because many games don't even support Native sharing between controllers and mice at the same time. When I bought it, it was advertised as a keyboard supplement with analog keys, not a controller. This detection causes issues more often than not and defeats the purpose. Is there an way to change the way it is detected?
