Thank you for taking the time to report this bug and helping to make Ubuntu better. 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-rc1 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. ** 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/1254581 Title: USB stops working after a while Status in System76: New Status in “linux” package in Ubuntu: Incomplete Bug description: After leaving my workstation for a while, and then returning, my USB keyboard and USB mouse stop working. Actually, all USB ports stop working. The peripherals are plugged into the USB hub on my monitor. When I return, and the monitor wakes up, USB is dead. Plugging them into other USB ports has no effect. As far as I can tell, the only way to fix this is to reboot. Is there a better workaround, like removing and reinserting a kernel module? I tried this with "ahci", but it gives me "Error: Module ahci is in use". Having to reboot every time is quite bothersome.
