arsenix, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: kernel-request-3.0.0-12.20 ** Tags added: bot-stop-nagging ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/862465 Title: Webcam uses excessive power even when idle Status in “linux” package in Ubuntu: Incomplete Bug description: Machine is an HP Elitebook 8540w. It is equipped with a Chicony webcam (USB ID 04f2:b15e). Powertop reported that this device was using around 2W of power even when idle, despite the fact that /sys/bus/usb/devices/XXX/power/level was reporting "auto". Explicitly setting the power/level to auto caused it to go into sleep mode, and powertop subsequently reported 0mW power consumption from the device. Likewise, explicitly adding a udev rule to set the power level to auto caused it to enter idle mode by default on bootup. After explicit setting of power level to auto camera still functions perfectly when needed and properly sleeps again after program exits. 2W is a significant amount of power even for this hog of a machine (typically uses 26W).
