> **Subclassed by:** [`AppleDeviceWatcher`](https://auscaster.com/icey/docs/api-reference/icy-av-AppleDeviceWatcher.md#appledevicewatcher), [`LinuxDeviceWatcher`](https://auscaster.com/icey/docs/api-reference/icy-av-LinuxDeviceWatcher.md#linuxdevicewatcher), [`WindowsDeviceWatcher`](https://auscaster.com/icey/docs/api-reference/icy-av-WindowsDeviceWatcher.md#windowsdevicewatcher)

Base class for platform-specific device change monitors.

Call [start()](#start-19) to begin monitoring and [stop()](#stop-10) to end. The watcher is NOT auto-started; callers must explicitly start it.
