I just received my FLIRC. I have a FireTV about 2 years old I think, not the cube, not the stick.
I also have a harmony 665. I programmed it for
FLIRC
FireTV.
Everything looks fine.
Synced the remote and then plugged in the FLIRC into the available USB port on the back of the FireTV. I turned the FireTV around so I had full direct line of sight and I get no response for any buttons, even directly in front of the dongle and lining it up. Am I missing a step?
