If it is not listed then probably your version of Poser does not think it is a Pro version, since only the Pro version has access to the Kinect. You may want to deactivate and reactivate your Poser 11 to see it that will cause the Kinect to show up. Otherwise you really need to get support help.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
