Plutonium

So I am trying to use a controller with the Plutonium launcher to play Black Ops. I am fine with using a mouse to launch the game in Plutonium but once the game is running I have issues.

Can someone explain how to get a controller working in legacy CoD games when launching with Plutonium rather than Steam?

Is there anyway to use the launcher with only a controller? Or if some way the controller can control the pointer?

I imagine there is something within Steam to do with controller support but I have no idea.

Just wondering if anyone has managed to integrate this launcher in a console like set up?

Thanks
