Velbus integration does not discover all my modules over USB

Third party integrations
1

I’m currently starting with home assistant. In my home I have a Velbus installation with quite some modules and panels. I have a raspberry pi 5 running HA OS hooked up to my system. After installing the Velbus integration and doing a scan over USB, the system always finds a few modules. However, the number of modules found seems to be different in every scan. One time I find 20, another time 31, even 60 ones. But never does it discover the entire system…
With the VelbusLink software, I never have issues scanning the network. I’m using the Velbus system a few weeks full-time now and don’t notice any poot Quality CAN communications either. It’s always responding fast and working great.

What could be the issue here? I tried: 3 different USB cables, different USB ports on my pi, reloading my configuration using VelbusLink, restarting HA and the integration multiple times,… What else can I try?

Have you tried the option suggested in the Velbus forum?

And have you carefully read & searched the topic on this forum?

This “onboarding” has been documented well and most of the bumps in the road have been addressed.
