Z-Wave network: it's gone!

Configuration
1

Using: Hass.io / RPI 3b+ / Aeotec Gen5 Z-Wave Stich & Arduino RFLink

Hi guys, first topic! New user, already managed to work on the system for 20+ hours.
Just yesterday I did a little dance because I was so happy it all went well. Did a alarm test, lights flashing, siren was on. Happy times.

Later that day I had to plug-in some USB-extension cables. That changed my life :wink:
A couple of hours debugging Z-Wave and RFLink are still DEAD. Non responding, Z-Wave no nodes. I donā€™t know what to do anymore.

The config in configuration.yaml

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

rflink:
  port: /dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_7573030313935150E101-if00
  wait_for_ack: False

As visible above, I made both persistant

usb-0658_0200-if00 -> ../../ttyACM1
usb-Arduino__www.arduino.cc__0042_7573030313935150E101-if00 -> ../../ttyACM0

The OZW_Log.txt keeps telling me:

ttyACM0? Itā€™s really not there. It doesnā€™t ā€œlistenā€ to the configuration.

My my my.

Itā€™s all back online.

What I did, and I really think isā€™t weird, I deleted the Z-Wave integration (Configuration-> Integration) within the frontend.
After a reboot it was back online.

This was happening to me many times over past year or so (Zwave stick gen 5).
Usually, if the stick is visible in HA but no other devices are visible (this happens most often) i just need to reboot Hass a couple of times and after some reboots it magically starts working again.
If the Zstick is not visible too, normally i need to switch Zwave stick to the other usb port and restart whole thing.
On one occasion none of the above was helping and restoring a backup of .storage folder had helped.
