Answer 3

I spent a night fighting this problem with my Doogee DG350, which runs the Chinese MTK chipset which has issues with USB on OS X. I found the solution was to run ADB in TCP/IP mode and then connect wirelessly:

adb tcpip 5555

adb connect 192.168.1.10:5555

adb devices

it's actually a bonus, cos you can dispense with the USB cable and debug wirelessly. Not looking back

So i did some research because the same thing happened to me. If the simple solution doesn't work you should check if you installed knox when you first launch your phone. If you did install knox the only way for you to activate usb debugging would be to reset your phone back to factory config in order to deactivate knox (aka not installing it again), apparently you don't have the option to unistall knox on recent phones.
