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!

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.
