Totally missed the posts but great to hear it’s solved with the solution included. Pretty sure it will help someone in the future
Thanks for sharing this, my VM on VBox was crashing after every update attempt for zwave addon. Changing to USB 3 fix it.
For what it’s worth, I had similar symptoms (trying to update Z-Wave JS UI beyond 3.6.0 would crash the VM and I couldn’t update Home Assistant because Z-Wave JS UI 3.6.0 was incompatible with newer versions) – but I’m using a different controller (Zooz ZST10).
I updated my Zooz ZST10 to the latest firmware and set the VirtualBox USB controller to USB 3 and that has solved my issue as well.
