title: Android adb hangs in list devices and other commands
body: <p>When I try to run adb commands from terminal, especially <code>adb devices</code>, <code>adb kill-server</code> and <code>adb start-server</code> it hangs and I need to type <code>CTRL+C</code> to exit proccess. Its not possible to deploy APK to physical or virtual devices. Something is block adb proccess/port. I have anti-virus uninstalled and firewall disabled.</p>
  
  <p>In the example below, I type adb devices and terminal show me <em>List of devices attached</em> and hangs in there.</p>
