Can I connect to USB2.0 with RealSense D435i?

Hi.
I have a RealSense D435i.

Is it possible to connect using USB2.0?

Stereo Module Depth stream cannot be displayed when connected to USB2.0.

RGB Camera is displayed but not in real time.

does anyone know?

Thank you very much.

  Hi Makoto Terabayashi

  Yes, RealSense 400 Series cameras such as D435i can be used with USB 2. Are you attempting to connect to the camera using a program script that you have written yourself, please?

   

  Because a USB 2 connection operates at a slower data transfer speed than USB 3, the number of supported resolution and frames per second (FPS) speeds is fewer than on USB 3.  For example, for the depth resolution 848x480 and 1280x720 will only support 6 FPS.

   

  A good test configuration to use will be 640x480 at 30 FPS as it works with both a USB 2 and USB 3 connection..
