SkyConnect checksum errors in Silicon Labs Multiprotocol logs

Hi,

I finally bought a EVE door and window sensor to start using my SkyConnect.
I do NOT use the SkyConnect for Zigbee (don’t have Zigbee, I do have Z-Wave).

My HAos is running as a VM on ESXi forwarding the USB SkyConnect to the VM.
I could not get it to work, it shows up in the Companion app on Android but it fails at checking network.

Went on to view the logs and noticed this/these error(s) in the Silicon Labs Multiprotocol logs:

I have no updates pending (except HA 9.1) now running the latest 8.x

Any thoughts?

I just noticed a document of Silicon Labs mentioning an incompatability of Bluetooth devices with Thread.
I removed my USB passtrough from my Home Assistant VM running in ESXi 7 U3o and rebooted the Sillion Labs multiprotocol addon. Error is gone… so this is not a ‘fix’, but this might get us in the right direction.

The problem with the device not getting past the network part is still there. I think the checksum error is not related. Mayve it can even be ignored?
