While I successfully connected this F710 gamepad set to “X” mode to a Jetbot (SD flashed with full 64 GB image) with the Controller registered at /dev/input/js0 as indicated by running “jstest” and “jstest-gtk”, and

Rebooted the Nano Jetson and the usual updates: sudo apt-get update, upgrade, list-upgrade, and "rsync jetbot/notebooks ~/Notebooks
However running the Teleoperation Notebook with index (1) or (0), no action.
I would appreciate any diagnostic steps.
My Diagnostic Actions
I confirmed that the Jetbot appears properly configured as the Basic_Motion Notebook works actuating the motors from a remotely connected Jupyter Notebook.
Here’s the Jupiter Teleoperation Notebook sequence from my Mac Safari Browser connected to the Nano Jetbot:
Create gamepad controller
The first thing we want to do is create an instance of the Controller widget, which we’ll use to drive our robot. The Controller widget takes a index parameter, which specifies the number of the controller. This is useful in case you have multiple controllers attached, or some gamepads appear as multiple controllers. To determine the index of the controller you’re using,
Visit http://html5gamepad.com.
Press buttons on the gamepad you’re using
Remember the index of the gamepad that is responding to the button presses
Next, we’ll create and display our controller using that index.
import ipywidgets.widgets as widgets
controller = widgets.Controller(index=1) # replace with index of your controller
display(controller)
Connect gamepad and press any button.
Even if the index is correct, you may see the text Connect gamepad and press any button. That’s because the gamepad hasn’t registered with this notebook yet. Press a button and you should see the gamepad widget appear above.
*** Nothing happens here***

Awesome! Our robot should now respond to our gamepad controller movements. Now we want to view the live video feed from the camera!
The Notebook cells that follow show that the Camera image functions work correctly
Further, 1) running https://html5gamepad.com displays the F710 id name, proper button and joystick operation. The name is Logitech Wireless Gamepad F710(Standard GAMEPAD Vendor 046d Product c21f.
2) On the Nano desktop Chrome Browser: Using the HTML5 Gamepad API to Add Controller Support to Browser Games has an html Demo that correctly reads the gamepad and displays the Button and Joystick status:
