Fix: USB Connection Listener CPU #66

libusb_handle_events_timeout_completed always returns (non-blocking). libusb_handle_events_completed will block for 60s. Calling libusb_hotplug_deregister_callback will trigger libusb_handle_events_completed. Hence why stop() must be called before libusb_hotplug_deregister_callback.

This resolves #64
