I have some patches around here from Pat that do the conversion of the USB subsystem to this new model. I'll go ask him if it's ok to post them. > > > As for how it affects the USB code ...

The check will be in the USB core, just like it is today. But we have to have the ability to fall down into the individual drivers to let them do the check, just like we do today (usbserial, usbstorage, usbvideo, etc.) > Does an error in init() mean that the system will give up on the device ?
