The usbgecko is hotplugable and hotswappable.
But as this is mostly a developer feature, not normaly used by end users, I think that we can just let it be as it is: autodetect it on boot (now probing for it instead of using information from the device tree).
If you unplug it later it causes no errors, you just miss whatever data is sent to it.
