There is a known hardware bug in the USB, i modified my Gen-5 with the new resistor.

Now the raspi 4 is able to see the Aeotec and presents the OCZ id like on the raspi 3B, but there is no communication. On domoticz on the raspi4 the device list is completely empty like after a hard reset. So is rollback everyrthing to the 3B again and the Aeotec is able to present all known devices again.
Aeotec on Raspi 4b no devices

There is some bad failure, the backup function did not handle and transfer the zwave session key. So the stick responds no devices and ignore all actions, this is a huge bummer. If everything must be ditched to the closet i will definitely ditch domoticz and start new with home assistant.
