Type-C (Thunderbold)

Hello,
I have a thunderbolt (type-c) on laptop. Recently, I discovered that my powerbank can act as a USB hub.

When I connect powerbank, I see the following on console:
Code: 
Nov 30 22:08:24 sphinx kernel: pci4: <ACPI PCI bus> on pcib1
So, no drivers attached automatically.
If I run devctl rescan pci4 I finally see the hub:
Code:

I thought we have hot plugging, isn't it ?
