You need to be more specific. How can you have trouble downloading a device to your Harmony remote? You either can or cannot add it to your account, and then you either can or cannot update your Harmony remote. ExpressVu is pretty common so the device should be in the Harmony database.

If you are having trouble controlling the 9200, maybe you need to change the remote address on the device (different remote addresses are used so you can have multiple receiver in the same room and still be able to control them independant of one another).
