Z-Wave AEOTEC USB Stick Error

Configuration Z-Wave
1

Environment: Raspberry PI 4. Buster. VENV install. HA v0.97.2 Aeotec USB Stick.

Background: This is my third HA Raspberry PI for HA. I’ve been a longtime user and upgraded PIs twice from my original install. On my original and second install, I had no issues with ZWave. Followed the instructions and it worked.

Problem: I’ve been wrestling with the USB stick on this install. I cannot seem to get it to be recognized. I would appreciate someone nudging me from my confusion.

Details:
The current errors I am getting in the log are shown below.
I have also included output from an ls tty command and dmesg.
Any hints on what I could look at next to get this USB stick recognized?
I’m out of ideas since I started this journey last weekend.

You will require an external USB hub to connect the Aeotec USB Stick to a Pi 4.

Well there you go! Excellent. Thanks. I could have been banging my head against the wall for a while more.

Found an old USB 2.0 hub in my electronics junk pile.
Hooked that up an BINGO, contact with the z-wave stick…

$ ls -ltr /dev/tty*|tail -n 4
crw--w---- 1 root tty       4,  7 Aug 30 15:00 /dev/tty7
crw-rw---- 1 root dialout 166,  0 Aug 30 15:00 /dev/ttyACM0
crw-rw---- 1 root dialout 204, 64 Aug 30 15:00 /dev/ttyAMA0
crw--w---- 1 root tty       4,  1 Aug 30 15:00 /dev/tty1

So there is my ttyACM0 that I have been looking for. Progress!!
Made sure homeassistant had permission:

$ sudo usermod -aG dialout homeassistant

Time to restart HA.
Checking the log…and…and…rats…
Time to keep digging. I would have never found that USB 2.0 hub thing though.

Looks like a spelling error. Took posting to see it.
