No, I know that, I'm just saying that's how I've always looked at it, and that's how lirc does it right now, not that it must be that way. > Do you expect all bluetooth input devices be presented > as a single blob just because they happen to talk to the sane receiver > in yoru laptop?

A bluetooth remote has a specific device ID that the receiver has to pair with. Your usb mouse and keyboard each have specific device IDs. A usb IR *receiver* has a specific device ID, the remotes do not. So there's the major difference from your examples. > Now I understand that if 2 remotes send completely identical signals we > won't be able to separete them, but in cases when we can I think we > should. I don't have a problem with that, if its a truly desired feature. But for the most part, I don't see the point. Generally, you go from having multiple remotes, one per device (where "device" is your TV, amplifier, set top box, htpc, etc), to having a single universal remote that controls all of those devices. But for each device (IR receiver), *one* IR command set. The desire to use multiple distinct remotes with a single IR receiver doesn't make sense to me. Perhaps I'm just not creative enough in my use of IR. :) -- 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
