Note, 4.4.0 is _very_ old for us to be dealing with here, I strongly suggest you file this in your distro's specific bug tracker, as they are the only ones that can support that kernel version for you. > Since the upgrade the battery indicator LEDs on my Logitech Performance MX Mouse > light up about every 60 seconds.

Why is this a problem? If you don't want this new feature enabled, you could disable the loading of the driver to the device by blacklisting it somehow in a modules configuration file somewhere (sorry, don't know how Ubuntu does this...) 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
