Hi. I've had similar problems and they seem to be caused by the camera being detected as USB2 device instead of USB3. I've tried with many different USB3 cables, and the only one I can get working properly is the one that came with the D435 camera.

If you are on linux you can check your camera by typing "lsusb -t" in the terminal. Check if the transfer speed is listed as 480M or 5000M. If it's 480M, the computer has detected the camera as a USB2 device

I also encountered this problem. The camera can only get the data of infrared 1 but not the RGB image, and it keeps reporting errors.

Did you solve this problem? I think it’s definitely not the result of the data cable
