title: Connect two Android phones with USB cable
body: <p>I want to connect two phones with USB cable and use ADB command like <code>adb devices</code>, <code>adb shell</code> from one phone, just like between PC and an Android phone. I tried with OTG supported cable which has two micro USB plugin, but it didn't work. Trying with another common cable (not OTG) with two micro USB plugin didn't work too. <code>adb devices</code> always fails with message "no device is attached at all" in both Phone A and Phone B.</p>
  
  <p>Anyone has experience about this? What kind of cable is needed?</p>
