Macbook Pro with Retina will not boot with Plugable 7-port 3.0 hub connected.

Model USB3-HUB7-81X
S/N - 109000o2314257

Four WD My Passport hard drives attached. Worked fine this morning but not this evening.


Sorry to hear about this issue.

If you disconnect the hard drives from the hub, will the computer boot with the hub attached?

Best wishes.
