Where do you plug in the Flirc on a Fire TV? Does the Flirc need to be plugged directly into the device it controls? Or is the Flirc like a Hub/Switch and it only needs USB power to work? I understand how to program the Flirc, but, I don't know where to plug the Flirc hardware into the Fire TV. So many people say it works with the Fire TV, but, I haven't really seen anyone mention where the Flirc plugs into on the Fire TV or only if the Flirc needs USB power after it's programmed. Thanks!
