USB3 hotplug. How to?

[lamacchiacosta]

Hello,
I just did a fresh install of Sierra and almost all runs smoothly.
My USB3 works nicely when devices are plugged in before system launch, but the hotplug doesn't work so I have to restart any time I want to plug a USB3 device.
Is there any setup I should look into?
Thanks.

It is typical with GenericUSBXHCI.kext (assuming that is what you're using).
Better to install supported USB3 hardware.

Hi,
thanks for your answer. The USB3 hardware I am trying to hotplug are all the USB3 external drives and keys out there.
Is there anything I should check and change in your mentioned file?

I'm referring to your USB3 controller.
Forget about unsupported USB3 controllers... install supported controller hardware such as an FL1100-based card.
