USB camera (Logitech) stops working until reconnected

I have Dell desktop computer with Ubuntu 18.04 and Logitech BRIO camera. It worked good with Ubuntu 16.04 and worked good for a few weeks after upgrading to 18.04, taking hundreds of shots. Then starting a week or two ago, it gets a few shots, sometimes 30, sometimes 50, and then stops working until it is disconnected and reconnected. I have another Dell desktop, also with Ubuntu 18.04 and the same camera, but that one has no internet connection and does not get updated. That one continues to work fine. I swap cameras, and the problem is still with this computer.

I reconnect camera and run this script for test, using fswebcam to get shots and save as jpg:

#!/bin/bash

for index in {0..100}
do
    echo shot $index
    echo Time: `date +"%Y-%m-%d %T"`
    fswebcam -d v4l2:/dev/video0 -r  4096x2160 --jpeg -1 --no-banner -S 9 --verbose temp/shot.jpg
    sleep 1
done
exit

It works good 20 to 50 times, and then fswebcam says "Unable to find a compatible palette format." This is output for two consecutive shots, the last that worked and the first that failed:

dmesg -T shows this, starting from when the camera was reconnected:

And that last thing is repeated many times.

I have tried this many times and it always fails the same way, starting with that "usb 2-8: Set SEL for device-initiated U1 failed."

How might I find and fix this problem?

As commented, I have a similar issue on Windows 10. I recently noticed a warning in logs mentionning that I was using the webcam with a 2.0 USB port (the only one left available on the computer). I switched to a 3.2 USB port, and no disconnection since more than one hour... I read at several places (like here) that the webcam only works as expected in 4K with the default / logitech cable or a full compatible one, which would need to be USB3 480mbs at least. So plugging it in a USB2 could indeed be problematic. As you use -r 4096x2160, you problem could be identical ?
