I am running flirc on RASPBMC and its setup pretty well and initally works ok with my remote however I leave my Pi on much of the time and when I come back to it Flirc fails to respond. It does seem to take hours of being left. XBMC is still working fine I can control it with the wifi App remote, but until I reboot XBMC flirc wont do anything. My other USB device (Hard Drive) is fine and still seems awake and responding. Any advice? Thanks
