I am not a big fan this bitfields but this is another story.
One thing you might want to add later (because we do one thing at a
time) is that you might want to prefer one kind of an endpoint. For
instance you want hold back "this-ep" and not give it away for INTR
because it can do double buffer and DMA and you would like to give it
away for 512bytes BULK type of endpoints.
Another restriction is that an endpoint can do INTR, BULK, ISO but has
only a 64byte sized fifo and you would like to give it away as soon as
possible.
