You can put a full speed device on the OTG port. It's an AB port so there's nothing hard about that. Get a miniAB to B cable and you're all set.

We already have a Tobi but it proves to only support high-speed devices. Unless I'm mistaken the only way to connect a full-speed device like an USB audio device is to connect it through a hub, which would complicate our design considerably if we want to keep it a single unit.
Except for the fact that the OTG port only delivers up to 100mA and the audio device requires 400mA.
The strange thing is that the OMAP3530's specifications include “High-Speed/Full-Speed/Low-Speed Multiport USB Host Subsystem”. Why does the port on the Tobi only support high-speed? Can it be switched to low/full speed mode? We couldn't care less if that would mean losing high-speed.
