Title:
  usb ports dies under certain known circumstances

Status in linux package in Ubuntu:
  Expired

Bug description:
  I bougth a brand new Lenovo Z710 for my mother in law who is near 80.  In stead of trying to teach her win8, I installed Ubuntu desktop 14.04 on it, without even bothering to go through the win8 installation. Apart from ubuntu standard software I've installed teamviewer (she lives 100km away), wine (there are some win programs she wants), a danish-english dictionary (under wine) and photofiltre 7 (under wine).
  It works like a charm right out of the box - except, if I boot or resume it with anything in the external usb ports, the external usb ports dies (not shure about the internal ones) ubuntu acts normal except the external usb ports - power is there but nothing gets detected. However if I boot it up without anything plugged in, I can later plug in an external mouse and hd's without any problems.
  I've googled and search everywhere without finding anything useful, I've tried an other kernel, I've switch form UEFI boot to legacy boot and back, I've tested the usb 2 and the usb 3 ports, I've reinstalled and I've of course tried an other mouse and other usb hardware  - everything without getting any wiser. The only thing I've not done is to install win8.
  From what I can see in dmesg (I'm far from an expert) the usb behaves normally untill right before the end of the boot process, the mouse are detected and installed but doesn't work and lsusb shows no devices at all.

  I've attached dumps of lsusb and dmesg in working and non-working
  state plus some additional information and really hope someone at
  launchpad can help out.

  Thanks in advance
