Any suggestions?

You are correct. It means the device is not supported. Is the P/N(found on the bottom of the controller) 863225-1000? There is the possibility, although very unlikely, that Logitech changed the PID of that device. If that is the case send us the joystick and Chicklet and we will fix it for you.
