Realsense Viewer Cannot Find D435i Camera
Hi:
I have both a T265 and a D435i camera. The T265 camera works great! I can get nice results on the Realsense viewer and get a ROS node publishing data.
The D435i camera however has a problem. I am running Ubuntu 16.04 and I have successfully installed the librealsense library on my system. I have followed the firmware update steps (for multiple versions 5.11.6.250, 5.11.4, and 5.11.1.100), For each of these versions, I run into a problem in step 10 of the DFU install steps:
intel-realsense-dfu -p
wherein I get the following response
---------------------------------------------------------------------------------------------
- Intel® RealSense™ DFU Tool v1.1.0-
Error: Couldn't find dev with busnum = 0 and devnum = 0
!
----------------------------------------------------------------------------------------------
This is a fixable problem because I can adjust the step 10 command to
intel-realsense-dfu -b 00# -d 00# -p
which works. Note that here the device number is always higher (usually by one) than the device number I called in Step 8. I'm not sure why that is. But I suspect that this may be the cause of the problem.
Finally, when I call the realsense viewer. The camera is not recognized.
Does anyone have ideas on what the problem may be and how I can troubleshoot this?
Thanks!

What computer hardware are you using please? In the past, the busnum devnum error has mostly occurred on single-board computing devices. Thanks!

Thanks for the computer information. Please check through the advice in the link below and see if there is anything that may be relevant to your situation.

So I have reviewed the issue and that appears to deal with Windows 10 whereas this is Ubuntu 16.04. I'm not sure how to relate the problems in that issue to mine.
My system is a dual boot however, so I did go ahead and test my camera in Windows 10. It works great! No problems there. But I want this to work with ROS, so I need to figure out what's wrong with this camera in Ubuntu. How should I proceed?

My expectation is that you are more likely to get useful advice on this from the version of your question at the GitHub, as there are very technically minded Intel engineers / developers and RealSense users there (my own specialization is Windows rather than Ubuntu). I see that somebody has already responded at the GitHub.
This guide may be worth a read though:
