** Tags added: apport-collected trusty ** Description changed:
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.
