In our in-production installation with 3 PC’s + 3 ZED 2i cameras installed for rock-climbing walls, we’re periodically hitting an issue where a camera will lose connectivity to the computer. It doesn’t appear to be isolated to a single system or PC, as it’s happened to multiple cameras now. It produces this error in our application (ZED SDK 5.4.0 C++) :
Jul 17 08:37:34 climb climb-app[2000]: [2026-07-17 08:37:34 UTC][ZED][INFO] Logging level INFO
Jul 17 08:37:45 climb climb-app[2000]: [2026-07-17 08:37:45 UTC][ZED][ERROR] CAMERA NOT DETECTED in sl::ERROR_CODE sl::Camera::open(sl::InitParameters)
The PC still sees the camera as a USB device (see outputs below), but it’s not able to interact with it, including testing with ZED_Explorer.
Neither application restart, or multiple PC reboots are able to resolve this issue when it crops up. The only way to resolve it has been to cut the cameras connection (unplug it), which would seem to suggest the camera hardware has locked up.
I want to note we are currently using a 10 meter active USB 3.0 extension between PCs and cameras while we await the arrival of the official StereoLabs USB cables we ordered a while ago (see topic). I suspect this is noteworthy because the cameras receive their power via power injection on the camera end of the USB extension, so their power is uninterrupted when the PC restarts, which is perhaps why PC restarts don’t fix it.
For context, these are running on:
- Arch based Linux (kernel
linux 7.0.14.arch1-1in production) - ZED SDK 5.4.0 (C++)
- CUDA 13.3.0
When the issue is present, the below is what we’re still able to fetch about the camera from the system, so it is connected, but unresponsive:
