Cannot connect time machine backup hard drive through a hub and the VGA multiport USB-C adaptor.
I have the VGA multi-port media adaptor. When it is connected to power and VGA monitor, I cannot connect any hard drives through a hub. I have a 4 port USB3 hub that normally works but not if it is connected to the multi-port USB-C adaptor.
MacBook, OS X Yosemite (10.10.3)
