So why are you going to audit anything based on it? :) Oh wait, it's worse, it is logging strings, which are even more unreliable than vid/pid values. It's pretty obvious this has not been tested on any large batch of real-world devices, or thought through as to why any of this is even needed at all. So why is this being added? Who needs/wants this? What are their requirements here? From what I recall, the author is just messing around with the USB subsystem and audit as something fun to do, which is great, but don't expect it to be mergable :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
