So you think? USB is hotplug, and it doesn't have to be a port in use
that you're unplugging.

OK, that makes things easier.

Perhaps un-/reloading the kernel driver modules (if compiled as module)
is sufficient anyways -- the module will probably reprobe everything upon
reload; OTOH you can check usbd and devd and things if you can pin
devices to certain ordering.
