Is there an easy way to "switch planes" for iteration within the IORegistry? Or perhaps I'm missing some fundamental concept. Essentially I've got USB devices that I'm finding through notifications. From there I want to discover information within the context of the service plane. It seems silly for me to have to start a the root of the service plane. Can IOUsbDevice act as a "via" to another plane? The specific context is I wish to discover the IOSerialBSDClients a device publishes. My thought was to get the USBDevice (such as in USBNotificationExample), then iterating the children of that device. This email sent to site_archiver@lists.apple.com
