The issue didn't start happening after an upgrade; in fact it happens when I newly installed the system. I thought a few kernel updates will heal itself, but it didn't so I decided to report.
Ok, I will test the upstream kernel using linux- image-3.19.0-031900rc6-generic_3.19.0-031900rc6.201501261152_amd64.deb, however i have quite a few modules like nvidia and virtualbox which are claimed to be "proprietary" or out-of-tree modules by the KernelMainlineBuilds page... -- 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/1416238 Title: USB randomly stops working on Kubuntu 12.04 Status in linux package in Ubuntu: Incomplete Bug description: I am using a laptop and all the USB ports will suddenly stop working especially when the laptop has been put to sleep and then resumed again (however the probability is very rare) .
