Use
This entry point is called in all devices when the DeviceFS directory structure is about to be read, allowing devices to add and remove non-permanent devices.
The path supplied will be full (eg $.foo.dojo) and null terminated.
Notes
Interrupt-driven buffered device drivers will ignore this call, as they do not sleep.
