I just purchased a Flirc and am trying to program one of my remotes (Sony BD). I am trying to test it using Potplayer under Windows 10. I am running 3.6 and always get: C:\Program Files (x86)\Flirc>flirc_util.exe keys Warning: cannot open USB device Recorded Keys: Index hash key ----- --------- --- 0 D190812F left_ctrl I 1 CF881170 left_ctrl+left_shift * 2 BAA77AC1 left_ctrl * 3 63A16936 +left_shift+left_alt+right_ctrl * Note in particular the "Warning: cannot open USB device". I get this every time I execute flirc_util! As an example, when i type in "left_ctrl+left_shift *" or better equvalent "left_ctrl+left_shift 8" in Potplayer the play/pause action is taken as it should be. When I hit PLAY on the remote nothing happens. It's as if Flirc isn't transmitting the keystrokes to the application. Any ideas?
