Description

Hello guys and thanks for your wonderful work and support on this repo!

Randomly, but really frequently, the zed_wrapper fails to turn on the cameras returning different errors such as: [ZED][WARNING] INVALID FUNCTION CALL in sl::ERROR_CODE sl::Camera::open(sl::InitParameters) [ZED][WARNING] CAMERA NOT INITIALIZED in sl::ERROR_CODE sl::Camera::grab(sl::RuntimeParameters)

All these errors are returned launching twice the zedxm.launch file in zed_wrapper on two different terminals specifying the Serial number of the two ZedX Mini cameras plugged to a Stereolab ZED Box through GMSL2 cables.

Any help on this?

Steps to Reproduce

1. Mount cameras
2. Launch the standard zedxm.launch file specifying the camera's serial numbers

Expected Result

Cameras and depth cameras correctly streaming in rViz.

Actual Result
