Usb usb1-port1: disabled by hub (EMI?), re-enabling

Camera model
HBVCAM 5M-AF

What is the problem?
So this is funny, because the setup has mostly worked before, but refuses to now. Whenever I print for a while and have my USB camera module connected to the Pi, either the webcam fails on it's own (hanging the webcamd service) or the serial communications get taken with it. I have boiled the issue down to the following dmesg entry:
usb usb1-port1: disabled by hub (EMI?), re-enabling...
Apparently, the Pi restarts USB randomly. This does not happen when the camera module is not connected, and also doesn't happen when the printer is not actively printing.

What did you already try to solve it?
Changing ports around, isolating USB cables to prevent possible EMI, swapping out cables, Adding powered USB hub for just the camera, both etc.
I have also tried running the camera way under spec (resolution, frames etc.) but that hasn't changed a thing.
Whenever both devices are connected and running at the same time, there is a high change the print will fail with the error. I have spent 4 days trying for a solution, the error has apparently happened to many Raspberry owners over the years, but I have not found a definitve answer as to WHY it is happening. To me it seems like the Pi just axes the USB controller when there is "too much" bandwidth used, but really the camera shouldn't be such an extreme bandwidth-consumer.

As of right now I am going to try a Pi4 I also have, seeing as it has multiple USB controllers to maybe isolate it somewhat through that. But really that's no solution, as there is no power issue and I can't understand the problem.

Additional information about your setup (OctoPrint version, OctoPi version, ...)
1.7.2, 0.18.0, respectively. Running on RPi 3B+

Hmm - there's two issues here that are almost exactly the same, I personally have not seen it before which seems strange. Have you done sudo apt upgrade recently that it might be an issue with a new firmware or something? You only have one webcam, the other poster had 3 - what resolution/FPS is it running at?

I've had this on my rpi before, and it's usually due to one of the USB connections not making a good connection, such as one of the connectors not being plugged in all the way or just fitting loosely in the plug. Vibrations or even just touching the cable can cause the connector to shift a bit, which I imagine causes the pins to connect/disconnect intermittently.

The fun part is that it could be any device on the hub and it will take everything down; in my case one printer was taking down both printers and a USB camera. I found that if I was using the SDcard in the printer (updating firmware) I was bumping that USB connection since it was so close and eventually enough vibration was caused during printing to cause this issue.
My fix was to completely unplug the printer from USB if I needed to use the sdcard slot at all, and then plug it back in afterward.

I have done upgrades afterwards trying to see if there was a fix, however I can not say for certain wheter I recently did upgrades prior to the first occurrence, but it is possible.

Welp, RPi4B+ doesn't seem to have the issue in the exact same setup.

The Pi 4 does have different USB tech to the rest of the lineup, maybe it's more resilient.
