Yeah, I like this approach.

I pulled it, looks good. Thanks a lot!
This also pulled your OTG patch and the fixes from "Minor USB issue".

How much does the stack depend on a STM32 controller? Would it be sufficient
to supply another driver struct to it to support other Cortex-M3's easily?
It would be awesome if we could reuse (most of) the code for other
microcontrollers.
