I see a lot of these too. But I also saw them on the zstick.
Other than the main Zigbee thread, there are a few threads from people trying to setup Zigbee on the HUSBZB-1.
I added a couple more devices tonight, shutdown OH, and put the quickstick in my laptop. I also get these errors, so not a sign that the stick is bad or a lead to why the restore wasn’t working.
My PID was also 8A2A.
In a support ticket from Aeon Labs, I had asked about restoring to the quickstick. In response, the tech included this in his reply “It pretty much a save state, so if the controllers NodeID is 51, thats what the backup file would have saved.” If the backup is just a memory dump of the nodes in the network, maybe the restore worked for me because I already had the quickstick in the same network (same as you have now done) when I tested the restore. Once I knew I had a good backup of the zstick, I played with so many things that it’s a little cloudy how exactly I got to the point to where I could backup/restore between the sticks. But you might have success with the restore now that it’s on the same network. Anyhow, glad you got the zwave migrated!
