Title: ZED 2i not detected on Ubuntu 22.04 with ZED SDK v5.0.7

Hardware:

  • Camera: Stereolabs ZED 2i

  • GPU: NVIDIA GeForce RTX 3060 Mobile (Max-Q)

  • USB: Direct connection to USB 3.0 port

Software / Drivers:

  • Ubuntu 22.04

  • NVIDIA driver: 550.163.01

  • CUDA: 12.4

  • ZED SDK: v5.0.7 (ZED_SDK_Ubuntu22_cuda12.8_tensorrt10.9_v5.0.7.zstd.run)

Steps Taken:

  1. Installed ZED SDK v5.0.7 using .run installer.

  2. Installed NVIDIA driver successfully; confirmed nvidia-smi works.

  3. Verified Secure Boot is disabled in BIOS.

  4. Checked USB detection:

lsusb | grep -i stereo
Bus 003 Device 005: ID 2b03:f881 STEREOLABS ZED-2i HID INTERFACE
Bus 003 Device 006: ID 2b03:f880 STEREOLABS ZED 2i
  1. Checked kernel logs:
sudo dmesg | grep -i zed
  • Shows USB connection but no ZED kernel module loaded.
  1. Verified permissions and added user to video and plugdev groups.

Problem:

  • ZED_Explorer and /usr/local/zed/tools/ZED_Diagnostic report “Camera not detected”.

  • lsmod | grep zed returns empty, indicating the kernel module is not loaded.

  • Tried reinstalling SDK, but camera still not accessible.

Hi @vansh_agg
Welcome to the Stereolabs community.

From the diagnostic:

"glx_info": "OpenGL vendor string: AMD\nOpenGL renderer string: RENOIR (renoir, LLVM 15.0.7, DRM 3.57, 6.8.0-85-generic)\nOpenGL core profile version string: 4.6 (Core Profile) Mesa 23.2.1-1ubuntu3.1~22.04.3

This means that the discrete GPU is not used.

Please apply the fix described in this support page: https://support.stereolabs.com/hc/en-us/articles/8422008229143-How-can-I-solve-ZED-SDK-OpenGL-issues-under-Ubuntu

Hi @vansh_agg
Please use cheese or guvcview to try to open the camera stream.
Is it visible? Can you change the resolution and grab rate?

hey , i found the issue there is a mismatch in the cuda version i have installed 12.4 and for zed sdk i have installed 12.8 .

you please give me the zed_sdk for cuda 12.4

That should not be a problem. The major version is important, not the minor.
