Perhaps he could add this > requirement to the API he's working with. I think that's entirely possible. It's up to how we want to describe devices.

The user would then need to check which entities have equal sysfs paths. -- Regards, Sakari Ailus e-mail: sakari.ailus@iki.fi XMPP: sailus@retiisi.org.uk
