In order to work with embedded systems on WSL2, it's needed to bind the device Serial Port on Windows to the WSL2 host. The project that allows that is usbipd-win.

To install it, open a new PowerShell terminal and execute winget install usbipd.

Once installed, list the available USB devices:

usbipd list

You should see an output should be similar to this:

BUSID  VID:PID    DEVICE                                                        STATE
2-3    0d28:0204  USB Mass Storage Device, Dispositivo Serial USB (COM3), D...  Not shared
2-4    046d:c52b  Logitech USB Input Device, Dispositivo de Entrada USB         Not shared
2-5    1bcf:2a02  Integrated Webcam                                             Not shared

On this example, the Serial Port BUSID is 2-3. Then, you must first open an elevated PowerShell promt and execute:

usbipd bind --busid 2-3

Then you can attach it to your WSL2 host without administrator privileges by running:

usbipd attach --wsl --busid 2-3

Expected output:

usbipd: info: Using WSL distribution 'Ubuntu' to attach; the device will be available in all WSL 2 distributions.
usbipd: info: Using IP address 192.168.64.1 to reach the host

Now, you can use the Serial Port on your WSL2 host.
