There are plenty of threads with similar questions in the dedicated Orbi forum.
Anwers and conclusions are alwas the same: The USB ports are for future use, there is no product decription claiming support neither for ReadyShare nor printing nor for any nother generic USB network port share.
Even if the Negear community state there is currently no support for ReadyShare, this does not imply it will ever happen. Querying almost off-topic in the Genie App forum won't help much - it would be a change required to the curent Orbi WiFi system components available.
