I have a OAK-D camera that recently has started to exhibit random crashes when I try to use it.

For example I am trying to run the rgb_preview example from the depthai-python repo.

Sometimes it works but sometimes it will crash the camera.

My OS is Ubuntu 24.04, kernel version 6.11.0-21-generic.

The output I get when the camera crashes is

[14442C10C1C5CAD200] [1.5] [1743336657.451] [host] [warning] Device crashed, but no crash dump could be extracted.

Traceback (most recent call last):

File "examples/ColorCamera/rgb_preview.py", line 30, in <module>

with dai.Device(pipeline) as device:

     ^^^^^^^^^^^^^^^^^^^^

RuntimeError: Device already closed or disconnected: Input/output error

Checking the logs I can see the camera diosconnects and reconnects to the USB multiple times:

    Looks like something is wrong with either the cable or the ports. The

    silviudr Mar 30 08:08:20 : usb 1-5: new high-speed USB device number 41 using xhci_hcd

    should be "super-speed USB device" for f63b (booted).

    Can you recheck?

    Thanks,

        Thank you for your answer Jaka.

        I tried another cable and another USB port. Seems to be working better but I still experience crashes.

        I am trying an application I implemented using mediapipe and while the application used to run the camera crashes with the following error message:

        terminate called after throwing an instance of 'dai::XLinkWriteError'

        what(): Couldn't write data to stream: '__stream_asset_storage' (X_LINK_ERROR)

        Stack trace (most recent call last) in thread 30433:

        terminate called recursively

        Aborted (core dumped)

          silviudr
          Then it's still the same issue. What about the bandwidth test?

          Thanks,
          Jaka

              Set Usbspeed inside bandwidth test to SUPER. It looks like you have a slow connection.

              Thanks,

                Thank you for your reply.

                I tried to set the USB speed to SUPER buit I got the same result.

                Is there any way I could flush the camera firmware?

                An interesting discovery. The camera is running as expected when is connected to a raspberry pi 4. I would exclude a slow USB port on my machine. My laptop is a gaming laptop purchased in January.

                I am running Ubuntu 24.04 LTS, kernel version 6.11.0-21-generic
