Report Flirc suddenly sending many keypresses on each button push in General Questions Posted November 2, 2014 I'll do that in the morning. I just eliminated everything else. Turned off all the lights and removed the USB extension I was using. I'll try the new firmware in the morning. I'm not recording keys, I'm using the FLIRC XBMC preset in the Harmony software. I'll followup later today. Don't rule out faulty hardware. In my case, simply swapping the flirc for a new one solved my issue. I didn't need to make changes to the OS, or XBMC or any of the other things many people here talk about.
