RasPi not seeing Z-wave Serial port

I have upgraded to OpenHAB 3.1.1 on a new RasPi 4. I moved my Aeotec Z-Stick Gen5+ over from the orginal OpenHAB 2 on a Raspi 3, to start setting up Z-wave devices and I am having trouble have setting up the serialport.

I have seen that I have a /dev/ttyAMA0 on the system but It does seem to be working. I have unplugged the Z-stick from the USB and then check the /dev directory again and no change. All of my google searching and troubleshooting thinks that it is a hardware issue not recognize the USB device.

Any insights would be greatly appreciated.

It’s a known issue between the Raspberry Pi 4 and the Aeotec Z-Stick. Just search for “Aeotec Raspberry Pi 4”.

The solution is to use a USB 2.0 hub.



I just got the 2.0 hub and got it working,
