I took a quick look at the mainline git log and there were quite a few usb changes between v3.13 and v3.16:

Because there are so many changes, we probably should perform a kernel
bisect, if we find the bug still exists in the latest mainline kernel.

Title:
  USB broken on Intel NUC (Ivy Bridge D53427RKE / BOXDC53427HYE) with
  Utopic Kernel

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  This bug is likely related, or at least has the same root cause as Bug
  #1350480, which specifically is affecting Trusty.

  I installed yesterday's daily Utopic build (and applied all updates)
  to an Intel NUC, which has worked very well for me with 13.10 and
  14.04 (except Bug #1350480).

  There are lots of different NUCs out there.  This one, in particularly
  is an Ivy Bridge D53427RKE / BOXDC53427HYE with i5-3427U CPU.  It also
  has 16GB of RAM, a 120GB Kingston mSATA SSD, a 2TB USB3 Western
  Digital external hard drive, a USB3 Ethernet adapter, and a USB
  keyboard/mouse.

  The installation completed successfully, but subsequent reboots
  rendered this machine unusable.  The USB/Keyboard and mouse were not
  usable in the OS (though perfectly functional in BIOS).  The USB
  Ethernet dongle was not usable.  The USB hard drive was not visible.

  Note that the test kernel provided at
  http://kernel.ubuntu.com/~jsalisbury/lp1350480/ fixed all of these
  issues.
