These really are "internal to the usb core" functions and variables, I am loath to export them as it requires that you "know" what the device type is of something without any recorse if you get it wrong. I commented on patch 2/2 about that. Could we provide a usb core function for you instead to help out? What exactly are you trying to get access to on the USB bus that you need to use here, the port or the device? thanks, greg k-h
