This approach is not particularly synchronous. Take the case of an add
failure: how long would an application wait before deciding that the new
device is not going to appear?

Hi-
Looks good. Questions: how can the user space tools verify the success

Echoing the device's location code (as found in the OFDT "ibm,loc-code"
property) into the "probe" attribute will notify ebus of addition
