Before starting the bisect, I would like to propose to test kernel I've uploaded here:
http://people.canonical.com/~henrix/lp1528140/v1/ It is simply kernel 3.13.0-74.118 with upstream commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") reverted. This commit is known to have caused regressions and could be the issue here. Could you please see if it solves this bug and report back? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528140 Title: USB hub stops working after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
