How do I know which device > announcements are for storage devices? And how would I map those devices to a bus? Speaking with Linux HAL in mind, I would like to see storage devices added to devinfo. It would be great, IMHO, to see da0 attached to uhub2 on usb2 on ehci2 when walking devinfo. As was previously mentioned, the only way to do this currently is to walk the entire list of cam devices, and string compare busesIt would be great if this was more easily attainable.
