I was able to use my Harmony, even though the STB says Cisco on the front, the bottom of the box says Scientific Atlanta (Cisco owned). When I first typed in the Cisco IPN330HD in the Logitech search software it came up blank, but when I searched just the model number it had Scientific Atlanta in front. I did have to use the learning function for the "Back" "U-Bar" and "Recorded Shows" but all the other buttons came in perfectly.
