The old dm "usb info" implementation has several issues:
- NULL pointer deref when a bus has no children
- Not showing usb devices on busses without an emulated root-hub (otg host)
- Attempting to show devices on inactive busses
- "usb info" Would cause some hosts to get re-probed something which only "usb reset" should do
TL;DR: proper iterating over usb bus root devs is hard, use the helper for it.
