For what it's worth, I am trying to use the same IR receiver in 14.04 on
a chromebox. I tried running 'apport-collect' but it wouldn't let me
since I did not create the bug. If there's another way I can attach the
report, please let me know.

Title:
  Z97 requires xHCI for USB2: IR remote unusable

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.10, kernel 3.17.0

  I have an HP MCE IR remote receiver that will not work on my ASRock
  Z97 based system, whether plugged into USB2 or USB3 ports. It is known
  that this device did not work in USB3 ports, but with the Z97 it will
  not work on either. The symptom is that when you use ir-keytable -t to
  display the scan codes for keys pressed, you will get inconsistent
  codes for the same key.

  The problem seems to be that Z97 requires xHCI:

  Due to the design of the Intel 9 series chipset, all USB devices connected to the
  USB 2.0 and USB 3.0 ports are controlled by the xHCI controller. Some legacy USB
  devices must update their firmware for better compatibility.
