Hello. I am using multiple ZED2i cameras.
Recently, after updating the ZED SDK from 5.1.2 to 5.2.0, oen of the camera is not being detected and working in ZED Tools.
The GPU and CUDA version are as stated in the message below, and the other cameras are functioning correctly.
OS: Ubuntu 22.04
- After updating the ZED SDK, I performed calibration using ZED360. (This was successful.)
- I recall that launching Depth Viewer and Explorer worked without issues. (Maybe, because the cam0 was not the crashed camera, but pretty sure)
- The camera index seemed to have changed from before, so I unplugged and replugged the USB port several times.
- When attempting to recalibrate using ZED360 to match the changed camera index, one camera persistently failed to be detected.
- Running diagnostic tool produced the following message:

** 수행해본 조치: reboot, USB port 변경, ZED SDK update 5.2.1, ZED SDK Downgrade 5.1., etc **
Still not work
문제가 뭔지 알려주시면 감사하겠습니다.
저희가 취할 수 있는 빠른 조치는 ZED SDK를 올바르게 Downgrade 하는 것일 겁니다.
저는 낮은 버전의 SDK 파일(5.1.2)을 설치 방법에 따라 실행하였고, 이전 usr/local/zed 를 삭제하고 진행하지는 않았습니다.
조속히 해결되길 기대합니다.
