User-Agent: Mutt/1.5.11+cvs20060126 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi! I made some quick experiments, and usb still eats 4W of battery power. (With whole machine eating 9W, that's kind of a big deal)... This particular machine has usb bluetooth, but it can be disabled by firmware, and appears unplugged. (I did that). It also has fingerprint scanner, that can't be disabled, but that does not have driver (only driven by useland, and was unused in this experiment). Any ideas?
