What I will say is the same problems exist after the latest update by Fanatec, so really need to get this sorted now it's been along time.
Updated to newest drivers but device disconnected/connected is still there. Its happening only in R3E so its probably game bug, not fanatec's fault.
Sorry bud forgot to come back to you, no problems this end what so ever, no messages of any form, and no disconnects, so all good.
