Hello,
I have another problem with RealSense D415, I don't get a depth stream. The Viewer report is : Starting Depth stream failure.
The RGB and INFRA streams are fine.
Yesterday everything was OK, today no Depth stream.
All the settings are the same as before. I have tried all the USB ports on my laptop, also, I changed the USB cable, but nothing, still no depth frame.
Why is this happening?

Hello Eliza,
Thank you for the quick response. I did exactly like you suggest me, but still nothing. No depth stream.
Also, I tried the D435 camera too, the problem is exactly the same.

Hello Eliza,
Both cameras has the latest firmwares.
I don't have another computer with USB 3 port.
Can I delete all the settings (even from registry) somehow and install everything again form zero?

I am not near the equipment now, I will do everything you suggest later and I will report you.
Yes, I am using the short USB3 cable from the box. The Viewer reports USB 3.2. connection with the camera.
How should I test the rs-capture example exactly? If I remember, that is an *.exe file? I should just run the *.exe file of the example?
Thank you for the help. I am sorry for these problems, but I am confused with this all day. Yesterday and almost 3 weeks before I got the infra, rgb and depth streams well. I haven't changed anything today and I don't get the depth stream.

Dear Eliza,
I tested the D415 like you suggested, still no depth frame, only the RGB.
Best regards

Hello Eliza,
I have uninstalled everything (software, driver, registry entries....), than I have installed again everything, but nothing. Still no depth frame. In Device Manager stays, that D415 works properly.
The Viewer recognized the D415 via USB 3 port as USB 3.2. connection. Also, the Depth Quality Tool has no depth stream too.
I am sending you the screenshot of the Viewer.
I am totally puzzled.
Thank you in advance.
Kind regards

Dear Eliza,
I tried all the presets, there were no depth stream.
I have tested on other computers the camera and it worked.
Finally, I uninstalled everything and I installed an older SDK (2.17. I think) and then worked the depth stream. After this I installed the newer SDK (2.18.1.) and it worked too. How long will it work, I don't know? I hope everything will be fine.
I think, there is a bug in the software or in the driver. The engineering team should check this.
I will report you if something will be wrong.
I have one more question about Matlab wrapper now. The pointcloud_example should give the XYZ coordinates and the point cloud (still I don't get the point cloud and I can't access the pointcloud object) the depth_example should give the depth image
But, which Matlab functions should give the RGB image and the INFRA image?
Thank you,
Best regards

Dear Eliza,
Yesterday the 2.18.0. and 2.18.1. versions didn't work again. I have uninstalled them again. I have installed the 2.17.0. version again and this version works since then (2 days).
I am sure that there are problems with the 2.18.*. versions.
Also, I have noticed one more interesting thing. Sometimes when I connect the camera, the Viewer recognizes the USB 3.0., sometimes recognizes the USB 3.2.!? This is interesting too. This is also an important point of view because the bandwidths are not the same with USB 3.0. and USB 3.2. With the USB3.2. the Viewer offers me higher resolutions.
Thank you.
Kind regards

Dear Eliza,
Sorry for the late response, I had some jobs to finish in last few days.
Yes, still I can't get the depth stream using the 2.18. version of the software.
I am using the 2.17. version, this version works well so far. I flipped the USB cable to, but the Viewer mostly recognizes the USB 3.0., sometimes the USB 3.2. Naturally, the offered resolution parameters are not the same.
I can't get the depth stream using D415 and D435 with the 2.18. in the Viewer and in the Depth Tool also (I've tested again both cameras).
I tried to uninstall and reinstall the 2.18. few times, but still no depth stream.
Also, the GUI of the 2.17. version is little different, than the 2.18. For example, I can't find the "Settings" tab in upper right corner of the 2.17.? Where can I find this tab in 2.17.?
Thank you for the help.
Kind regards.

Dear Eliza,
The 2.17. version works fine so far, but I can't find some tabs, for example the Settings tab in right upper corner (like in 2.18. version).
I don't know what is wrong. I have tested the Win7 version on other laptop (on Win7) and it worked well.
I think there is a software bug. I have updated the display driver too, but still no depth frame. I sure that is a software problem here.
I will find an another Win10 computer to test it again, but firstly I need to finish some research work.
Thank you for your help, it means to me very much.
Best regards
