As it says at the bottom of that page:
The Host Stack currently has the following notable limitations:

No HS (High Speed) support

No Hub support (currently only supports a single device)
So yes, it's a software limitation, the hardware is capable of talking to hubs just fine. I don't think there's anything closed-source in the software that drives USB, so technically a capable programmer with enough time could add hub support themselves. (But please poke us first if you're planning on doing that.)
Hello, planning to investigate adding USB hub support...poke! :D

Any thoughts/suggestions?

Thanks! I poked the people responsible for the USB stack; hope they'll chime in on the work that needs to be done.
