This was done deliberately.  The relevant standards state that a USB
device can have no more than one peripheral interface.

Does building a kernel image that can run on different hardware without 
rebuilding also violate the "relevant standards"?

No.  That isn't what Arnd was concerned about.  He noted that even if 
you did build multiple modules, only one of them could be loaded at any 
time.

And who's to say that there aren't multiple USB devices on a single 
board, that just happen to share a CPU and memory? :-)

That's why I don't fully support this decision.  But I wanted to point 
out that there _was_ a conscious decision, as opposed to bad 
programming through sheer carelessness.
