We _need_ that protection!
We _have_ that protection because only device drivers that claim an interface, perhaps via probe(), are allowed to use that device. To repeat: the protection doesn't need to be explicit in the driver programming interfaces. On the other hand, usbdevfs doesn't necessarily bother to claim interfaces when it makes control calls. Since that's internal to usbcore, I don't think that undermines my point. It's already got its fingers in lots of places "real drivers" aren't allowed to go. - Dave _______________________________________________________________ Have big pipes?
