I assume no concerns over something that could be attached to a port on
the hub... I guess for a cold unplug it probably won't matter so much.
For the usb hub coldunplug, I find a concern. If a usb device attatched
to a usb-hub, then we coldunplug the hub, how will the hub and usb device
look like? All disappear OR all remain?

As I know, for scsi and scsi controllers, it is all remaining :)
