Ok, I have some more info. I'm now using the stock cable that came with the device. Additionally I've added my main workstation to the list of tested computers (last week I was working remotely on my Linux/windows laptops). Unlike my Linux laptop. I have not updated this computer since the last time I was successfully using the Oak-D-S2 on it.
When plugging the device in to my work station, I get a single output in my Dmesg log:

When using the stock cable with my Linux Laptop:

When using the stock cable with my Window's laptop, the errors are unchanged from my previous photo.

I think its clear to me at this point that whatever is going on is agnostic to the cable or OS/computer. All three of these machines have successfully run the camera before with both our project's code and Luxonis' example libraries.

[UPDATE]: Additionally, I've plugged in an Oak 1 Lite we had lying around and it works great on my workstation!

    Hi pkyleUPI ,
    This, unfortunately, does look like a hardware issue. Could you contact support@luxonis.com, and link them this discussion link, so we can replace the device?
    Thanks, Erik

        I have five cameras connected to a laptop using an active USB extender. However, one of the cameras randomly stops working with an X_link error related to limited bandwidth. Everything works fine when I limit the USB speed to High. Any help would be greatly appreciated. Noted that sometimes everything works fine without any issues.

        Thank you.

          Thanks for the reply. I noticed that the problem is because of active USB extender, I changed the cable and I can get enough bandwidth.

          Hi again. While the error was absent for a few days, it has reappeared this morning. Everything was working fine until last night. I am checking the bandwidth and noticing that it reduces to Downlink: 335.6 Mbps, Uplink: 221.0 Mbps (using luxonis/depthai-experimentsblob/master/random-scripts/oak_bandwidth_test.py). If I set maxUsbSpeed = dai.UsbSpeed.SUPERPLUS, I get an Xlink error, so I have set maxUsbSpeed = dai.UsbSpeed.HIGH.

            Does usb speed remain around the same each time you test now? What changed? Did you restart the host, used a different port, things like that? Try setting UsbSpeed to SUPER and retry.

            Thanks,

              Previoualy I saw the speed is aroufn 1800 Mbps and now it is 300. If I put UsbSpeed to super, I will get X_link error. I just truned off the camera for the first time in the last 5 days and rerun it again, so the error appears.

              As a solution, I unplug the entire cables and replug them and now it works. I am not sure what the problem is and how to avoid it using the software

                Thanks for letting me know! We'll be looking at USB issues.

                  Thanks a lot for the help. I was wondering if there is update as I can see my bandwidth randomly changes using active cable extension

                    Difficult to say what the cause is. An active cable should only amplify the signal and shouldn't affect the bandwidth. Perhaps there is a latency buildup which causes this.
