The USB-UIRT has been great so far (with Girder). BUT, I can't seem to get it to learn one remote button, which has one function when pressed once (mute) and another when held down for 3 seconds (off). If I just try to learn and press it, it learns the single-press function then quits after 1 second. I can't seem to get it to learn for the whole 3 seconds so it catches the whole code from beginning to end.
Is there any way around this?
