Drobo 5D

has anyone used a USB 3 HUb with there Drobo 5D to shared the drobo between 2 computers? I can only see 1 computer, Drobo software won’t detect the 2nd pc.

You’ve connected two computers to one USB hub? Oh boy. How did you manage this in the first place? That’s not how USB hubs (well, USB in general) work. And that’s not how direct-connected Drobos work. Undo this connection before you fry something (unless the damage is already done).
