  <p>All of these apps worked fine (at least was found) with iOS YouTube application.</p>
  
  <p>When I'm trying to find these "devices" (receivers) in my app with</p>
  
  <pre><code>self.deviceScanner = [GCKDeviceScanner new];
  [self.deviceScanner addListener:self];
  [self.deviceScanner startScan];
  </code></pre>
  
  <p>none device is found. No <code>GCKDeviceFilter</code> is used, I just want to see all cast devices on network. I'm using <code>GoogleCastFramework-2.2.1-Release</code>.</p>
