    infrared streams missing on raspberry Pi 3

    ENLITEON

      Hello, I am trying to open an infrared stream on raspberry without success.

      I tried both on Raspbian Stretch and on Ubuntu Mate for raspberry.

       

      On a PC -usb3 and the same camera I am able to use realsense-viewer to see both left and right streams.

      Using usb2 on the same PC I can only see one IR stream + depth.

      On the raspberry, usb 2, I can see none.

      Being that I also miss low resolution modes on the raspberry, it does seem to be an issue with modes not available for some reason.

       

      Thanks, ENLITEON

       

      On both raspberry installation the utility "rs-enumerate-devices" returns the following:

      NOTE that no IR streaming modes are listed

      NOTE: checking again what follows I just noticed that rs-enumerate-devices thinks the interface is USB1. Why?
