Hi,
I tried to migrate from RPI3 to RP4.
I did image of current version and then with second card I started rpi4. Everything seems to work correctly with one small “detail” - zwave. I have Aeotec controller but RPI4 doesn’t see it.
My serial is not listed
ls -l /dev/serial/by-id
ls: cannot access ‘/dev/serial/by-id’: No such file or directory
I have also zigbee controller but it discovered correctly
Did I missed something?
After switching to RPI3 controller works correctly
sudo dmesg | grep tty should show what devices the OS sees.
There is a known bug with the Aeotec and the RPi4. The has to do with the USB3 controller. A workaround is to connect the stick to a USB2 hub.
see: Pi4 && Aeotec Z-Wave USB Stick Gen5 - Raspberry Pi Forums
Although that is true the error stated indicated an incorrect device name. The stick would still be seen bu the OS, but as a non-functional USB3 device .
Below outputs

What are you using on the Pi 3? Looking quickly the device for both may be /dev/ttyAMA0.
It is zigbee controller
I bought USB 2.0 hub and controller is now available in the OH.
Thanks for a hint!
