In the “lsusb -t” (“tree” view) the camera is missing. In the non-tree view the camera shows up. It shouldn’t be possible for a device to be visible in one view, but not the other view (it’s two views of the same model). Was the camera plugged in at the time of the tree view? If it was, then this is indeed a very strange problem.
Just to note, in tree view the keyboard and mouse are connected to an external HUB which is in turn connected to the USB2 mode root HUB (the HUB which is internal to the system…this is the connector on the Jetson itself). The USB3 mode root HUB has nothing listed when in tree mode. For your particular case, is the camera plugging into the USB3 port, or to a HUB which is on the USB2 port with mouse/keyboard? If the camera goes to a HUB, is it powered or unpowered?
The detailed “lsusb -vvv…” may be missing information (probably not, but I want to be sure). Could you try using sudo?
sudo lsusb -d 046d:0809 -vvv
I see on the Logitech web page the camera is USB2, so there should be nothing missing regardless of whether the camera connects to a USB2 port or a USB3 port. Also, the web page about this camera indicates it is standard UVC, so no special drivers should be required.
If you run “dmesg --follow” you should see the dmesg output live as it occurs. Start without the camera plugged in, then show what the output is as a result of plugging in the camera.
