Does any one use it for Unity3D?

I really would like to, but unfortunately it´s not very compatible with Unity.
Maybe you can manage it to work in the editor, but when you have your executable you need special plugins… :-x
I just met a 3dconnexion-guy and told him about these drivers problems, but he said it´s up to unity-guys to make it work.
Great answer 
, he looks like doesn’t care much about over 1 million Unity developer 
I will try to make plugin using shared memory
Absolutely!
It has an extra axis so it doesn’t fit with the current joystick system for unity. It seems he is right, it would be easy for the unity guys to add it. However his product isn’t wide spread enough for the unity guys to care i assume.
I already found the way to get data in Unity3D. Please check this link: Trying to use csMonitor code - 3Dconnexion Forum
