MAC os service for usb insertion and removal

Question

i am trying to create a service for mac that triggers a python file whenever a usb is inserted or ejected in the system. My code works for this functionality but when i shut down my pc and restart the device the service randomly triggers the python script even when i have not inserted any usb.

launchctl_daemon_usb_trigger(){
    plist_name=$1
    plist_path="$plist_name.plist"
    plist_filename=$(basename "$plist_path")
    install_path="/Library/LaunchDaemons/$plist_filename"
    trigger_name=$2

    # echo "installing launchctl plist: $plist_path --> $install_path"
    log_message "Service Name <'$plist_name'>"
    log_message "Install Path <'$install_path'>"
    log_message "Setting up trigger event named <'$trigger_name'>."
    log_message "Creating the launchd service <'$plist_path'>."
    log_message "Executing command: <$PYTHON3_DIRECTORY $ETC_PYTHON_ENV $trigger_name>"

# Set the content of the plist file
cat <<EOF | sudo tee "$install_path" > /dev/null
