Persistent Naming for USB devices

I have a Texas Instruments TI CC2531 USB CDC [zigbee contoller]
when inserted into the Pi, HA says it is at:
/dev/serial/by-id/usb-Texas_Instruments_TI_CC2531_USB_CDC___0X00124B0014D956FC-if00

however, there is no such directory; it appears udev is not creating correctly.

Has anyone followed - and got - a solution to

# Configuration

## Automatic

You can use an USB drive with HassOS to configure network options, SSH access to the host and to install updates.
Format a USB stick with FAT32/EXT4/NTFS and name it `CONFIG` (in all capitals). Alternative you can create a `CONFIG` folder inside the `boot` partition. Use the following directory structure within the USB drive:

```text
network/
modules/
modprobe/
udev/
authorized_keys
timesyncd.conf
hassos-xy.raucb
```

- The `network` folder can contain any kind of NetworkManager connection files. For more information see [Network][network.md].
- The `modules` folder is for modules-load configuration files.
- The `modprobe` folder is for modules configuration files (/etc/modprobe.d)

Easy !
Juste used this permanent device name in your configuration.yaml or your addon configuration!

For instance: my Zwave configuration in configuration.yaml :

zwave:
  usb_path: /dev/serial/by-id/usb-0658_0200-if00

And my Zigbee2mqtt configuration file :

serial:
  port: >-
    /dev/serial/by-id/usb-Texas_Instruments_TI_CC2531_USB_CDC___0X00124B0018E275BC-if00
  disable_led: true

yes - that allows the device to work, but cannot use zigbee2mqtt with it, because that directory is not created.
Also - you are mixing zwave and zigbee - they are not the same protocol

Of course I can use Zigbe2MQTT to work with it… What what I wrote is exactly what is written in my Zigbee2MQTT configuration, ans it has been working perfectly for months now !

And I’m not mixing ZWave and Zigbee, I use both at the same time for different needs. That was just 2 different examples of how you can use the USB persistant name in HA configuration files.
