Hello xbo -
Photoshop requires a 3Dconnexion plug-in. As long as Photoshop CC is installed and closed when the 3Dconnexion software is installed, the plug-in is installed automatically with a complete install.
If Photoshop CC is installed after the 3Dconnexion software, you can install the 3DxPhotoshop plug-in using the Repair function in Programs and Features with Photoshop closed.[Windows Control Panel - Programs and Features - 3Dconnexion - Change - Repair]
You can check your Photoshop CC plugins folder to verify whether the 3DxPhotoshop plug-in - 3DxPhotoshop_CC.8li - is present.
Once the 3DxPhotoshop plugin is installed, pan and zoom are available in 2D images and 3D navigation in Photoshop's 3D menu. The default Photoshop display has the image the same size as the window so you will need to expand the image to pan.
For other applications, what is needed is not for the Space Navigator to recognize applications - it is the application that needs to be able to recognize input from a 3D device.
A 3D device is not recognized by Windows in the same way a standard 2D device or mouse is. A 3D device is in the category 'Human Input Devices' and applications need to be able to make use of this kind of device. 3Dconnexion provides a free Software Development Kit for software developers to add the ability to recognize 3D devices to their applications.
In the current driver, emulation of a 2D mouse has been added for web browsers and Microsoft Office.
You can find the list of programs that recognize 3Dconnexion devices
here.
A few of the applications - Google Earth for example - have settings inside the application that need to be enabled. In the Google Earth Tools menu under Options, Navigation
Non-Mouse Controller , check 'Enable Controller''.
