After setting up ADB , the first command you would run to test if you have a connection is:
Code:
adb devices
Instead of your serial being displayed, you might be greeted with an unauthorized screen like:

You should then receive a prompt on the device (ensure your device is awake and not behind a lock screen) asking you to authorize the adb connection. If you don't get this prompt on your device then run the following commands:
Code:
adb kill-server
adb start-server
adb devices
The prompt should look something like:

You are to tick the box then tap OK.
Now, run the connection-test code again
Code:
adb devices
Your command history should look something like
