I have tried using python script to open camera. But i always get a error report as follows: [2025-03-25 06:02:09 UTC][ZED][INFO] Logging level INFO [2025-03-25 06:02:09 UTC][ZED][INFO] Logging level INFO [2025-03-25 06:02:09 UTC][ZED][INFO] Logging level INFO [2025-03-25 06:02:09 UTC][ZED][INFO] [Init] Depth mode: PERFORMANCE [2025-03-25 06:02:10 UTC][ZED][ERROR] [Init] Unable to capture images.

To address this issues, i check my usb port: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/5p, 20000M/x2 |__ Port 1: Dev 116, If 0, Class=Hub, Driver=hub/4p, 5000M |__ Port 4: Dev 117, If 1, Class=CDC Data, Driver=cdc_ncm, 5000M |__ Port 4: Dev 117, If 0, Class=Communications, Driver=cdc_ncm, 5000M |__ Port 4: Dev 3, If 0, Class=Hub, Driver=hub/4p, 5000M |__ Port 5: Dev 126, If 0, Class=Video, Driver=uvcvideo, 5000M |__ Port 5: Dev 126, If 1, Class=Video, Driver=uvcvideo, 5000M

It seems to meet the requirements. Thus this issues, i can not open my camera, help me.

my camera is zed 2i, with ubuntu 22.04. I can use the sdk zed_explore and zed_depth_viewer provided by the platform normally.

Thanks.
