[SOLVED] Raspberry PI4, OpenHabian, Aeotec Z‐Stick Gen5 USB Controller

Setup, Configuration and Use Installation
1

  • Platform information:

    • Hardware: Raspberry Pi 4 Model B, 2GB
    • OS: openhabian
    • openHAB version: openhabian-pi-raspbian-201908050414

  • Issue of the topic: Z-Wave Serial Controller is offline. I saw the Z-Stick once with lsusb, but it disappeared after restart. There is no change (lsusb or dmesg -w) when I insert or remove it. I tried a fresh installation, but the result was the same.

Z-stick is ok. I tried it in Windows OpenHab installation.
USB port ok. The USB drive is operating normally.

Any idea what’s wrong?

  • Console command output:

If you had searched for RPi4 and Aeotec here or on the Inet you would have found information about electrical issues with that combination. Guess you have to change HW.

Thanks for notifying me of the HW problem. I was looking for a problem in the OS. The solution was brought to me by an old USB HUB. The Z-Stick connected via it works well.
