this might look better if you would something like the list_for_each()
macro.
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?
What op[1] meant was to create a for_each_ep_desc() macro, eg. (not
tested):
#define for_each_ep_desc(it, start) \
for (it = (start); (it = next_ep_desc(it)); ++it)

You have the same comment (including the same typo) here and in the .c.
Please use only on (in the .c file) as they will go async.
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?
There's none. That's the problem. Someone will modify comment in one of
them
and will forget to modify it in the other. That's why it's better to keep
comments in one place only.
