I am looking for a word which meaning is the opposite of "usage". The context is the use of devices of any sort. The best I've come up with so far is to look at the situation from the devices perspective and consider "usage periods" and "inactivity periods".

Idle time or idle periods could be what you are looking for. The term is already in use in the computer and other industries to denote time when a machine could be working but isn't.
