This happened to all devices. The information is still there from going to other applications still though. This change occurred when I updated RME to 4.3.1.

Ah, I think I know what happened. The PIDM database still has the devices linked to RME 4.3, but the version of RME is now 4.3.1. The fix requires an SQL query to be run against the cmf database. Open a service request with TAC, and they can walk you through the steps.

FYI, I reproduced this locally, and it is what I thought. The PIDM entries still reflect the old RME version number. I filed CSCtc21648 to track this. If you contact the TAC, they can walk you through correcting the database so that the RME data is restored to Device Center.

Thanks for the info! I've got the same issue now that I've upgraded to RME 4.3.1. Will open a TAC case referencing that bug.

I've got the same issue with LMS 3.2 and RME 4.3.1.

The workaround I've found was to delete all the devices from DCR and rediscover them.

Do you know if that "bug" is referenced ?

The bug I filed is easily worked around without deleting your existing devices.  However, the workaround requires a direct database query, so you will need to open a service request with TAC to have them walk you through the procedure.
