at some point after connection to powered usb hub it would return: Couldn't open ./H_t265_d400.cfg

[AndreV84]

we managed to run the rs-tracking-and-depth using 38 version of sdk; is there any option to save pointloud from there? is there any option to get information from three sensors l515, t265, d435? or from 4 sensors 2xd435, 1x265 & 1x l515 with it?

I have same problem (Couldn't open ./H_t265_d400.cfg). Is there any solution yet?

[AndreV84]

yes there was the file accessible from some third party repository, as I recollect; otherwise try to find the file at the filesystem

[LinusNEP]

Great! I got it work now. Thanks
