ADB device list is empty [duplicate]

Question

I have the latest version of Android Studio and an Android device.

I turned on developer mode on my device and plugged it to my lap top via USB. I didn't get the prompt message that asks me to authorize USB debugging with this pc and also my device list was empty when I ran on the cmd adb devices.

I tried to do adb kill-server and then adb start-server but the devices list was still empty and I still didn't got any authorize usb debugging message on my phone.

I tried to restart phone + PC + change USB cable but nothing.

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.
