Aeon Labs z-wave Stick (S2) with Raspberry Pi 4

Configuration
1

In reading posts here and elsewhere I understand that many people have managed to get the above combination to work by plugging in an unpowered USB2 hub into the Pi and then plugging the zwave stick into the hub.

I just got a usb2 hub but cannot get the Pi 4 to recognize this zwave stick . I have tried every port on the hub as well as every usb port on the PI. I know the hub is working fine because 1) the stick is getting power once I bott the PI . 2) A thumb drive into the hub is recognized by the PI
This is the hub I am using

Is there something I need to do in the PI configuration? Can someone guide me through the process they used to get this to work?

Thanks in advance

The log file clearly shows the stick cant be found

  File "/srv/homeassistant/lib/python3.7/site-packages/openzwave/option.py", line 81, in __init__
    raise ZWaveException(u"Error when retrieving device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))

I tried another USB2 hub and had the same results :frowning:
Here is what I get when I execute ls -l //dev//tty*

I believe that the stick is Bus 001 Device 005 ID: 10c4:ea60

Anyone?

SOLUTION: I was booting the Rpi4 from a USB flash drive with a SD card I created months ago. Worked fine for anything else I was doing but decided to recreate the sd card with the latest raspian (buster lite). Modified the new cmdline.txt file to boot from the USB and … voila… everything worked…
