That's a possibility, yes. It should work until someone adds another
device there for some other purpose.

Why? What's wrong about checking for null ?
Or maybe checking for both not null and  not UCLASS_BOOTDEV ?

Not that I care too much, just to understand your reasoning.

Or can we check for recursible devices somehow ?
Maybe flag them or something ?

Why is better to state all devices are recursible except some UCLASSes
(meaning they can have stuff that needs listed in usb info - or
likewise usb tree -) instead of stating that some closed set are
recursible ?
