I went through the instructions to build librealsense, that went fine except a few hiccups, but it did finish
(instructions said to not do the kernel patches, I did not do them)
When I run realsense-viewer, it simply cannot detect the connected camera, the terminal shows:

I can run lsusb and get

I did connect it to the USB 3 port
I did do the "./scripts/setup_udev_rules.sh" part but I had to use sudo, because without sudo, it said "need to be root"
I've enabled the experimental OpenGL through rasp-config, and rebooted, I've rebooted many times during all this
I've installed Cheese but it didn't detect anything, showed me blank
The camera works perfectly fine on Windows 10
I spent the day installing ROS Kinetic Kame on Raspbian Buster and handled quite a lot of problems but now I am a little lost at this final problem, without a good error code to search for, I cannot find much help across the internet.
What should I check next? What info do you need in order to help me?
Thanks

There are a couple of possible approaches to installing Librealsense for Raspbian Buster. The first method is to install using libuvc without kernel patching.
https://github.com/IntelRealSense/librealsense/blob/master/doc/libuvc_installation.md
Another is to follow the advice from an Intel team member in the link below.

Thank you! I think that worked, realsense-viewer is now detecting the camera, I can get both depth and RGB, and it's currently performing a FW update to it.
