Multiple WD My Books, can only see 2 at a time?

I purchased a 3rd WD My Book drive yesterday. I currently have two other WD My Books attached to my PC (running Windows 7, 16gb memory, using a USB3 connection).

Problem is, My system does not see the 3rd drive.  If I disconnect one of the other drives and attached the new one, it sees it fine. Then try to re-attached the drive I disconnected…no luck. I’ve tried many combinations of connections, but always seems to only allows 2 My Book connections at a time.

Any clues as to what is up?

Thank you!
