I think the proposed API could be simplified. There's a hard upper
limit on the path length (7 ports including the HC) so I would
suggest to drop the path_len input parameter and document that path
must be uint8_t [7] or longer.

Please explain this comment in more detail? Does it refer to the
libusb_device refcounting?

Are all devices refcounted by their children?
