# Handle loss of a device

If paired Input Devices disconnect during the session, the system notifies the [`InputUser`](xref:UnityEngine.InputSystem.Users.InputUser) class. It still keeps track of the Device, and automatically re-pairs the Device if it becomes available again.

To get notifications about these changes, subscribe to the [`InputUser.onChange`](xref:UnityEngine.InputSystem.Users.InputUser) event.
