As the title states, I am unable to record any button presses via the GUI. I have tried multiple USB ports on two different computers (one PC, and one Mac), and more than one remote control. In all cases, the UI says to "press the button to be paired", and no matter what I press, nothing registers. I assume the Flirc itself is faulty, but I'm hoping there's something simple I'm missing. The device is recognized fine by both machines, and has the drivers installed and identifying the device properly. I also cleared the configuration and forced the installation of the latest firmware (which was already on the Flirc). Windows 10 Ent., and OS X El Capitan are the OSes I'm trying with. Thanks in advance for any ideas.
