-The current code is broken: it does surprise removal which crashes guests.
-
-Reimplemented the steps:
- - Hotplug triggers both 'present detect change' and
-   'attention button pressed'.
-
- - Hotunplug starts by triggering 'attention button pressed',
-   then waits for the OS to power off the device and only
-   then detaches it.
-
-Fixes CVE-2014-3471.
