Camera recognized but /dev/video not there

Hello, I have a generic webcam that I’d like to work in combination with MotionEye.
I use the latest stable version of Hassio and HomeAssistant as the day of today.

But unfortunately, I can not make it work, I need my webcam to create some kind of stream file under /dev/video*, but unfortunately, there is none and I do not know how to proceed.

If I were using some Debian based system and not hassio+buildroot I could probably install v4l-utils as many forums suggest, but I have no idea how to do this in Buildroot.

Do you guys know how to install v4l-utils in Buildroot, or any other approach in order to make my webcam available in MotionEye?

I have searched quite some pages in google but could not fix it, the only alternative I know would go back to Raspbian + Homeassistant which is not supported anymore.
