Hi there!
Thank you for your reply.
I ran a simple Python example that sets up a pipeline for Yolov4 object detection, and got the same result. I also ran another Python example that creates just a color camera pipeline to record a video file. Again, I got the same result.
The result of a "dmesg | grep usb" command for the two above cases are exactly the same, except the timestamps, of course. Here it is again (the first run is at timestamp 423.658683 and the second run is at time stamp 649.450393):
dmesg | grep usb
