ZZED 2i Not Detected and Blue LED Not Turning On

Hello everyone,

I have been using a ZED 2i camera with a Jetson AGX Orin for a few months without any major issues. However, one day the ZED 2i was suddenly no longer detected by the system, and the blue LED on the camera did not light up as usual.

I have already tried several troubleshooting steps, including:

  • Tightening and reconnecting the USB cable

  • Changing to another USB cable

  • Connecting the camera to a USB 3.0 port on another computer

Unfortunately, the camera is still not working, and the blue LED still does not turn on.

Has anyone experienced a similar issue before? I would really appreciate any suggestions or guidance on what I should check next.

Thank you very much.

Hi @Unn-Phakapol-S
Welcome to the StereoLabs community.

We need more details about your device’s status and system configuration to gain a clearer insight into the cause of your issue.
Could you connect the camera to the USB3 port, launch the ZED Diagnostic tool, and send the contents of the report file it produces?

Have you tried opening the camera with a Webcam application to verify if the video stream is available?

Hi,

Thank you for your response. I connected the ZED 2i camera to a USB 3.0 port and ran the ZED Diagnostic tool as requested. I tried to attach the ZED Diagnostic report file, but I am currently unable to attach files because my account is still a new member on the forum.

I have also tried opening the camera with a webcam application to check whether the video stream is available. However, the ZED camera was not detected in the webcam application either.

Thank you very much for your help.

You can copy and paste the content of the file to this thread.

This is important information. Please send the content of the diagnostic file to proceed further.

Thank you for your reply.

As requested, I have copied and pasted the content of the ZED Diagnostic report into this thread below. Please find the diagnostic report content below:
