I am using a Roku 3 model 4200x. I have a Roku activity set up on my Harmony 700. It works fine but I am unable to teach the Harmony new buttons. After plugging the Harmony remote into a USB slot of my laptop and selecting the Roku device, the Harmony software gives me a list of Roku buttons which can be learned. I select one from the list, hold the remotes facing each other and then press that button on the Roku remote. the Harmony screen tells me "ready to learn", but absolutely nothing happens. The Harmony remote doesn't seem to be recognizing the signal from the Harmony remote.
I've searched through posts on both the Roku and Harmony forums but can't find my specific issue.
Darn! So there's no work around to teach individual button commands?
