** Description changed: 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. + 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. + --- + ApportVersion: 2.14.1-0ubuntu3.19 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC2: mdoube 2897 F.... pulseaudio + /dev/snd/controlC1: mdoube 2897 F.... pulseaudio + /dev/snd/controlC0: mdoube 2897 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=8629e880-0342-46f8-9392-7b5444e0ef96 + InstallationDate: Installed on 2015-10-12 (112 days ago) + InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64+mac (20150805) + MachineType: Dell Inc.
