Frank FeuerBacher, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.19-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-1.80 ** Changed in: linux (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1405907 Title: Z97 requires xHCI for USB2: IR remote unusable Status in linux package in Ubuntu: Incomplete 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.
