Getting started with AI on Jetson Nano Course Startup

Problems with this course at the very beginning to set up the nano

I got a Nano, flashed the SD card, booted the nano, use the Logitech 720p camera recommended. Connecting by USB from MS Edge on a Window PC. Connecting is very intermittent, often no connection, sometimes it does. I go to the Jupyter notebook and try to get the camera working. I have never seen an image from the camera. The problem comes in the 4th step to make the widget. Server Connection fails usually. Previous steps Ok; Please help. I want this course.
