Max data speed into STM32F4 Discovery via the STLink/V2

I was looking to use the STM32F4 Discovery board as an output device which requires a significant bandwidth from the supporting PC.  I don't have specifics nailed down on this task, 115.2Kbaud might be sufficient but "more would be better".

I see the STLink offers some 2-way communication for ICD, but I don't know much about it.

Isn't the STLink just a virtual com port?  Can we run it at other speeds?  Or is it very limited for data transfer because it needs to retain the programming and debug capability?

Would it just make more sense to use the second USB port, configured as a generic HID and not a Host?  Again, what kind of bitrate could I expect to see?
