Interaction with 3DConnexion

I’m trying to use 3DConnexion Space Navigator (3D Mouse) with OpenGL. Does anyone have experiences using it? Please advise…

This is more of an input device question than an OpenGL question.
Download the SDK available on the Connexion website.
It has examples in multiple languages of multiple methods for getting input from the device.
Then use the appropriate input (translate, yaw, pitch, roll, etc.) to move whatever you are using for your OpenGL camera.
This would be done exactly the same as with a mouse or key controlled camera.
