We don't have one upstream, but we have lots of different ones floating around in different products at the moment, all of them seeming to only do one-off things (i.e. only work for one specific device.) How is this going to be integrated into such a future scheme? Are you working on this larger task? Or working with others who are? Any ideas of when this will happen? 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
