How does it confuse anyone? (also note that /proc/bus/usb/devices is not used in modern distros, it's in a different location now.) Why not fix your tools to report things in the correct order if you really care about it? The bus number means nothing except a unique id, it does not matter if things are sorted or not in the debug file. Actually, in the lsusb-rewrite I am doing, the userspace tool does the sorting, no need to change the kernel. So, sorry, I'm not going to accept this change. 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
