No camera connected - Docker

[chiuwe]

Hi All,

I'm trying to get my USB3 basler camera running in a docker container. I got all the gstreamer stuff and related plugin installed, as well as plyon5. I run my docker container with --privileged. When I run lsusb I can see that the camera is detected by the container.
Bus 003 Device 024: ID 2676:ba03 Basler AG
However, when I try to start a gstreamer pipeline, the debug window tells me that there's no device connected.

Does anyone have any idea where I should go from here?

I've never personally used a USB3 Vision camera in a container, didn't even know it was possible actually, I thought containers (at least VMs) only passed through USB2. Are you able to see the camera with the Pylon Viewer? I'd also give Aravis a try.

ok, so I got it working by forwarding all usb ports to the docker container.
Does anyone know where the usb camera gets mounted?
It didn't look like it showed up anywhere in /dev.
It is unclear to me from the dmesg log where the usb camera is actually mounted.
Does anyone have any idea?

BR.
