Answer 1

I know I'm 4 years late but my answer is for anyone who may not have figured it out. I'm using a Samsung Galaxy S6, what worked for me was:

1. Disable USB debugging

2. Disable Developer mode

3. Unplug the device from the USB cable

4. Re-enable Developer mode

5. Re-enable USB debugging

6. Reconnect the USB cable to your device

It is important you do it in this order as it didn't work until it was done in this order.
