The function next_ep_desc() goes over the endpoint descriptors (struct
usb_descriptor_header). It's not a list so I don't see how the
list_for_each() macro can be used here. Am I missing something?

Thanks for noticing that! 
What do you mean by "they will go async"? Is there some sort of automation
that updates the comments for functions from c files to the headers? I'm not
familiar with such...
