Is the ZED backward-compatible with USB 2.0?

The USB stereo cameras (ZED 2i and ZED Mini) are UVC-compliant USB 3.0 cameras. When connected to a USB 2.0 port, the available bandwidth is not sufficient for the full video stream: the maximum supported resolution is VGA at 30 FPS.

For this reason, we do not recommend using the cameras on USB 2.0 ports. Always connect the camera to a USB 3.0 (or newer) port, preferably on the rear panel of the computer and directly wired to the motherboard controller.

If your camera is detected as a USB 2.0 device even if it is connected to a USB 3.0 port, see How to fix USB 3.0 bandwidth and connection issues. To extend the cable length while keeping the full USB 3.0 bandwidth, see Can I use the ZED camera with a USB 3 extension cable?

Note: the GMSL2 cameras of the ZED X family do not use USB; see Can I connect the ZED X and ZED X Mini to a USB3 port?
