Hi Prodigy,
This is a very difficult problem for me, hope you can help!
I have installed Android Studio 2.1.1, when I click the run button in Android Studio 2.1.1 window, I got "No USB devices or running emulators detected".
Note, I have connected my mobile with USB and from my computer, I can see the files in my mobile.
I guess I have 2 or 3 USB drivers including Google USB Driver inslalled in my computer.
Hence, I want to know why the Android Studio 2.1.1 sayd "No USB devices detected".
