No, it was just to make it consistent. The context was being used some
places and some places not. Well, I saw the comment and wondered why
it was not used at that very spot , but I guess it was because there
was some work to have the context passed through the whole chain of
functions :)

The alternative would be to not use the context anywhere. It is not so
useful for a small, free-standing program. But it follows the book,
and if at some point the code will be embedded in a bigger program
doing other libusb stuff, it can only help.
