Jetson nano 2gb not showing /dev/video

I do not find this manufacturer in the USB manufacturer ID list. Perhaps they are new and the database I’ve viewed is not yet updated. It does mean I cannot look up the specs with the ID though.

The above says this is probably a stereo camera, and is running at USB2 speeds. The root HUB is itself only capable of USB2 speeds. If the camera is actually intended for USB3 speeds, then apparently the signal was downgraded and reduced to USB2. If this is actually a USB2 device, then the stereo camera is operating as expected. If not USB2, then the camera is operating correctly, but not using its full capabilities.

The dmesg content suggests USB2 is correct and not a downgrade. Looks like this also identifies the manufacturer as “lihappe8 Corp.”. Software has determined that this is a standard interface device and does not need a custom driver (at least for the camera port…some cameras will also have control hardware which might be custom, but I see no indication of this being the case). The UVC driver is correct for the device, and USB is trying to hand off this device to the UVC driver. The UVC driver is failing to work with the device.

The reason why the UVC driver is failing to work with the camera is unknown. This does not look like a signal quality issue. Instead, this looks like a quirk in the camera. There are many USB devices with such a quirk, and there is actually a lot of kernel code in existence for adjusting to quirks, but this device is likely so new it isn’t known. One reason I say this is because I did not find the manufacturer ID in the USB database. One would need to have the camera available long enough for someone to adjust for such quirks…I just doubt this has been visible long enough for someone to fix the issue.

Still, there is some minor possibility something else in the software is an issue, but this is a tiny probability. It would be interesting to see, when you monitor “dmesg --follow” on a desktop PC, what messages occur upon plug-in of the camera. Do you have a Linux PC you can examine this with and post the results?
