Sensor became unresponsive

You’re right, we do have no USB expansion cards.
Do I have to install a USB expansion card for it to function properly?

I tested different configurations by removing individual cameras and using only four sensors, but the issue persisted. Even when reducing to three sensors, the disconnection frequency decreased but still occurred.

I also noticed that the problem only happens when using Unity LiveStreaming—Depthkit alone does not cause any interruptions.

Ultimately, I found that lowering the voxel count in Unity’s Mesh Source to a certain level prevents the disconnections, but this significantly reduces visual quality.

Do you have any recommendations for maintaining stability while preserving better image quality?
