Application stuck on "Waiting for device"

まだ誰も着手していません。

## Issue template

- Hardware description: STM32L4 IoT Disovery Kit
- RTOS: Zephyr 10.2.0
- Installation type: Installed through https://github.com/micro-ROS/micro-ROS_sensors_demo
- Version or commit hash: 7fd84a2664fbfcc8aaccd4c483b3e87114272673

#### Steps to reproduce the issue

Run the application on an Ubuntu 22.04.3 VM on a Windows 11 machine
Launch the application normally through "Docker-compose up -d"

#### Expected behavior

Board is recognized

#### Actual behavior

App stuck on "Waiting for device"

#### Additional information

I've tried everything that came to mind, the connection is there, the firmware is properly configured and the board is recognized. I granted every access permission I could think of, as well.

I'd really appreciate any help or advice, and please let me know if you'd like me to provide more information.

Update: After days of trying, it magically seems to have resolved itself. However, when I list the ros2 topics in my terminal, nothing seems to appear. When I try to publish on the LEDs, it can't find any subscriptions either.

Start by reproducing the issue with docker-compose up -d on the stated Ubuntu VM and inspect the application output while the board is connected. Verify whether the device is recognized and whether the expected ROS 2 topics and LED subscriptions become available; the issue provides no file or test entry point.
