D435i not recongized

How can we get the D435i to work properly?? I know the notes say it won't get recongized, but there must be some way?! Are there any other external patches or something? Jetson Hacks made a video about connecting a nano to a D435i and they got it to work there.... what did they do that isn't included in the git?!
It is difficult to tell from your description the issue you are experiencing.
The notes were not updated at the time of the release of the video, everything should work.
Is the firmware recent enough on your camera?

Hi! That's peculiar then that mine doesn't work. I also just tried updating the camera to the latest FW on my host computer, then plugged it back into the jetson nano and still nothing (nothing as in the device is not recognized by the nano) :(
sorry, to clarify the issue I'm experiencing is that the camera is not being recognized by the nano despite installing all the patches and updating the Firmware
I just re-flashed the SD card, and re-installed everything by following your video exactly and the same error persists, no device is recognized when the D435i is plugged in, but works just fine for the T256
Just for reference, did you:
- Use a swapfile
- Compile with CUDA support
yes to both
What is the result of:
$ lsusb -t
Are you using a USB hub?
Are you running from a USB drive?
output:

I am running from the micro SD card (64BG) and not using a USB hub, just the available USB ports on the device
oh oops- that's the result of just lsusb
the results of lsusb -t are as follows:

One more question, how are you powering the Jetson Nano? Are you using the MicroUSB connector, or powering it through the barrel jack?
the microUSB connector
That's probably the issue. I'm building up a system to test it out.
Ok, I think I located the problem and fixed it. You will need to download the new installLibrealsense repository (tagged version v0.8 as a marker for people later on). The offender was in patchUbuntu.sh.
There are a couple of ways to proceed. You can run patchUbuntu again (and skip over the requests to Revert the previously applied patches). Or, if you're less trusting like I am, you can delete the directories /usr/src/kernel and /usr/src/hardware and run patchUbuntu.sh again from the installLibrealsense directory. Please let me know if this works.
I appreciate your patience and perseverance. This has been quite a little project, it's been difficult for me to test. Good luck!
This worked! Thank you!
I did as you said and deleted the directories then reran the patches.
thanks again for all your help!
