I must admit I am baffled. The patch in question only affects the EVIOCGKEYCODE path whereas '-a' means "automatically load appropriate keymap" and as far as I can see it does not call EVIOCGKEYCODE, only EVIOCSKEYCODE... Mauro, any ideas? BTW, I wonder what package ir-keytable is coming from? Ubuntu seems to have v4l-utils at 0.8.1-2 and you say yours is 0.8.2...
