Can anyone confirm if you were able to get the Mono Price 5x1 HDMI switcher to work with Harmony?

When I try to add a device if only shows it as a 4x1. Were you able to get the Harmony to learn the other input button successfully?

Never mind,
I confirmed that you are not supposed to the the model number REV 3.0, but rather HDX 501. Codes seem to all be there.
