This sounds like a distro problem, not anything the kernel does, as it does not mount usbfs on it's own, and never has. What distro and version are you using, and have you asked the distro developers about this yet? > If this was changed in .29, I can live with that...

It will be very hard to even build in usbfs that you can mount at /proc/bus/usb/ as it is not anything that is needed anymore by userspace, and only causes problems. 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
