Title:
  USB3 devices are not active early in boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  
  lsb_release -rd
  Description:	Ubuntu 14.04.3 LTS (up-to-date packages)
  Release:	14.04

  USB3-plugged devices do not function early in the boot process. This
  includes USB2 devices plugged into USB3 ports, but does not include
  USBx devices plugged into USB2 ports (these work fine).

  To reproduce:
  1. plug keyboard into USB3 port, computer off
  2. boot
  3. attempt to select options in the GRUB menu

  Observed outcome:
  Selection of boot options is not possible

  Expected outcome:
  Selection of boot options is possible

  Also, a few people have noticed that they can't boot from media
  plugged into their USB3 ports, for example a flash drive with a Live
  CD image on it. (e.g.
  http://ubuntuforums.org/showthread.php?t=1628665)

  I guess this has something to do with whether the usb3 drivers are
  available at this early stage of boot: later on, after the full kernel
  is loaded, USB3 works fine.

  I know I could plug my keyboard into a USB2 port as it was before, but I have these new monitors that have got only USB3 ports on them, and it's physically more convenient to plug keyboard & mouse into them than the workstation itself (Dell T7600), which is a bit far for the cables to reach.
