I assume you are using the 'auto-enum' feature?
I have seen this error when the first time the device was detected, I had an error in my YML configuration for that device.
Literally, the error means the device was half-created, the creation failed & device was deleted, yet the CHANNELS for the device were left behind. So future detection of the same device fails first because it cannot recreate it's channels.
That 'orphaned channel' issue will be fixed in a future Dia, however you'll still need to discover & fix the YML problem.
So turn off the auto-run, start you dia manually and watch for any errors related to that device.
