Interface IDeviceEnumerator

Enumerates input devices and produces IInputDevice for each enumerated hardware device, alongside their supported device.

There is only one IDeviceEnumerator service per instance, which is unique to the OS, and must enumerate all devices and their input drivers (API) for that operating system.

All IDeviceEnumerator must provide a keyboard device that implements the driver instance for Keyboard and a passthrough device that implements the Passthrough driver instance at a minimum, otherwise emulators will be unable to map inputs.
