Title:
  since kernel update USB NOT WOKING ANYMORE

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  - OS: Kubuntu 14.04.01
  - Kernel 3.13

  - Automatic security updates with MUON notifier.

  since kernel update 3.13.0-5x the usb ports on my notebook Acer E1-532
  do not respond.

  --> 3.13.0.61 generic does NOT work
  --> 3.13.0.61 lowlatency DOES WORK

  Problem is that virtualbox 4.3.10 kernel implementation will only work
  with the 3.13.0-65

  Another problem is that I provided my family and friends with Kubuntu
  14.04.01, because I thought LTS was reliable?

  I understand that HWE follows the needs of hardware development, but
  no usb  at all in  14.04 LTS version with automatic updates activated
  in muon notifier will necessarily lead to a total catastrophe of no
  usb at all.
