I have the same issue with my Lenovo x220 laptop, but in my case it's the integrated webcam
Here's the offender: 19.0 W 100,0% Device USB device: Integrated Camera (Chicony Electronics Co., Ltd.) After removing the uvcvideo module it gets slightly better but the problem remains: 13.1 W 100,0% USB device: Integrated Camera (Chicony Electronics Co., Ltd.) All the Powertop settings are Good, including USB device autosuspend for this USB device. I am now running 12.10 but I am going to update to 13.04 soon to see if this reproduces there too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/276791 Title: Powertop reports a USB device is active 100% of the time.
