Ok thanks again
So I will explain my issue:
We'll have a customer with 400 network devices in the snmpcollector.
This customer has an account in USM, with ownership of its own origin, let's say the origin is "google". And the snmpcollector is installed on remote HUB, let's say with the origin "apple".
So, when a user from this account will logon to the UMP/USM, he will only see devices within the origin of google. So the 400 devices will only be present if I gave him ownership of the origin "apple".
Is there any workaround for this, or is our setup wrong?
