Camera Zed2i not detected under Ubuntu 18.04 and 20.04

Hardware ZED2
1

Hi
I am using a PC Omen desktop with GTX1080TI, which has 3 OS (Win10, Ubuntu18 and Ubuntu20).
Under Win10 I have no issues in viewing Zed2i with different SDK tools. Diagnostic and explorer all ok.

Under Ubuntu 18 and 20, however, the camera is not detected. I connected it to all possible USB ports of my PC, but the diagnostic tool says “camera not detected” when testing the camera. SDK, processor and graphic tests are ok.

If I run lsusb I get the following (but no names of the device after the ID)
Bus 001 Device 007: ID 2b03:f881
Bus 001 Device 005: ID 2b03:f880

if I run dmesg I get the following

Any advice?
Thank you

Hi @guyver30 he latest update of the Kernel of Ubuntu broke the connection between the UVC kernel driver and the ZED SDK because it changed the way how a parameter is handled.
We already solved the problem and the fix is available in the ZED SDK release v3.6.5:

Thank you very much. That worked!

Does this also mean, that I cannot use the ‘zed-open-capture’ library to record raw images? In other words, I necessarily need the SDK and thus CUDA to use my ZED2i?

edit. Seems I am able to stream video in Ubuntu with the ‘zed_open_capture_video_example’
