Bug Description

[Impact]
Hotplug a USB3 device to HP dock can go undetected.

[Fix]
Add a delay for USB3 hub resume routine so the link has enough time to
transit to U0.

[Test]
After the patch is applied, the dock can always detect USB3 devices.

[Where problems could occur]
A non-noticeable delay was added, so no basically no impact.
