This answer reminded me of a question I've been mulling for a while.
Is there an easy way to associate a Quartz Event with the
corresponding USB device?
I've written a Keyclick program that provides adjustable audio
feedback for keyboard and mouse input using a Quartz Event Tap.
Suppose I want to play a different sound depending which keyboard an
event comes from (laptop built-in vs external USB)?
I haven't found anything in the Quartz Event documentation that
associates a device with each event, but I could easily have missed
something.
Thanks!
