Simultaneous Xbox 360 controller and Mouse support?

[flab]

I am thinking of picking up SOMA but have a technical question regarding how inputs are handled. Is it possible to move using the left analog stick of an xbox 360 controller in the left hand while using a mouse in the right hand to aim the camera? Or, are they mutually exclusive inputs, so that if the xbox controller is active the mouse no longer works (or vice-versa).

Also, is there analog movement so that if you move the analog stick a small amount you move slowly, but if you press it further out you move faster?

Thank you for taking the time to answer my question!
