The device availability test is actually there for a reason. Some firmware implementations put all the potential devices in the tables and only one (of some) of them are available. Could this be implemented so that if the node is a software node, then get its parent and then see if that is available? I guess that could be implemented in software node ops. Any opinions? -- Kind regards, Sakari Ailus
