Signal emitted when a remote caller is invoking the ScanDevices D-Bus method.
If a signal handler returns true
, it means the signal handler will handle the invocation (e.g. take a reference to
invocation
and eventually call
complete_scan_devices or e.g. return_error on it) and no order signal handlers will run. If no signal
handler handles the invocation, the UNKNOWN_METHOD error is returned.
