Title:
  USB 3 unreliable

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  None of my external hdd's or sdcard reader are working on my usb3
  ports under ubutnu linux 14.10 (also not on ubuntu 13.10 and stoped
  working either after an early update during 13.10 or 13.04, can't
  remember).

  lately i decided to report the bug and here is the syslog snippet while i tried writing to an external hdd with ntfs. it disconnected and reconnected.
  http://pastebin.com/qXHX6pHN

  
  on another hdd with ext3 formated it just caused io errors. i do not have the logs anymore and may post them if i get the device back again. similar issues with my external sd-card reader.

  all of these devices work fine on usb 3 under windows and worked also
  fine some time in the past under ubuntu.

  i try to update this when i can repeat the issue (currently none of
  this devices are available for me ut will be in the near future).
