Just to clarify on this one, you're missing a step. We get the scancode, and its passed to rc_keydown. rc_keydown then looks for a match in the loaded keytable, then passes the *keycode* that matches the scancode along to input_event. If you fix the keytable to contain system and command, everything should work just fine again. Throwing away data is a no-no though -- take a look at recent changes to ir-kdb-i2c, which actually just recently made it start *including* system. :) -- Jarod Wilson jarod@xxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
