Clip baord does not handle auto-changing modes. That is done when you change vehicle types (from plane to tank or vice-versa). When it changes the HOST posts a message to the text buffer notifying you of the change.
If the stick is not in the drop down list in the "Map Controllers" panel, then check to see if Windows is seeing it (via the Control Panel...Joysticks or Gaming Devices, on the System Device Manager...it depends on which version of Windows your computer uses).
