Hello again,

I tried this on my device and succeed to reproduce your problem.  
It turns out that you probably should install `udev` and start the service on your container.

I could do it with your example C code and following `Dockerfile`

```auto
FROM debian:bullseye

RUN apt-get update &&\
    apt-get install -y build-essential libudev-dev udev

WORKDIR /test

COPY code.c .
RUN gcc -o code code.c -ludev

CMD service udev restart && ./code

```

Let me know if it solves your issue.
