I am using CM4. I have observe kernel logs when USB2.0 issue occurred. Below is the screenshot:All of those properties come from the camera as it is enumerated over USB as part of the USB Video Class specification, so it's a fair assumption that the camera returns something totally different under some conditions.
The other command that would be of use would be "v4l2-ctl --list-formats-ext" which should tell you all the formats, resolutions, and frame rates that the camera is claiming to support. I suspect that will be changing too.
There is nothing inherently different over when the Pi enumerates the USB devices. Check the kernel logs for whether it is re-enumerating at any point, and check "lsusb -t" to ensure it is always connecting at the same data rate.
Also what version of Pi is this? CM4 or Pi5?
