That's fine as long as it's EV_IR_SEND event type, which can be trivially added. EV_KEY will not work here, as EV_KEY doesn't get passed up, since it's not possible to physically press a key on the remote by software action. The keys and the transmit ability will have to be treated as different event types, but that's it. > Does this node know it was created > by /dev/uinput Will the event written to /dev/input/event* then be > readable on the corresponding /dev/uinput handle? The kernel knows it, and it'll pass it to the uinput for reading by the appropriate process/handle. -- Vojtech Pavlik Director SuSE Labs ------------------------------------------------------------------------- Take Surveys.
