Andrei Dobrea, as per http://www.acer.com/ac/en/US/content/drivers an update to your computer's buggy, insecure, and outdated BIOS is available (1.32). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Description changed: 1. Normal boot up (either from the internal HDD or from the usb stick Kubuntu Live Session) 2. Mount the usb stick and then unmount (get the "Safely remove" message, but do NOT remove the stick from the usb) 3. Restart the laptop (let it boot-up using the internal HDD) Expected: next session should recognize USB devices (even if it won't "see" the device I left in the USB, it should at least detect its removal or other new devices) Actual: rebooting with the USB device still plugged in (after the "safely remove" message) somehow disables all the USB ports of the laptop; no matter if I remove the device afterwards, the USB ports activity no longer gets detected until another reboot. + + --- + ApportVersion: 2.14.1-0ubuntu3.19 + Architecture: amd64 + AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: zmb 2352 F.... pulseaudio /dev/snd/controlC0: zmb 2352 F.... pulseaudio + DistroRelease: Ubuntu 14.04 + MachineType: Acer Extensa 2510 + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-83-generic root=UUID=49bf7b42-01d5-4ba6-9049-c495c5a6e20e ro rootflags=subvol=@ quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.13.0-83.127-generic 3.13.11-ckt35 + PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon. + RelatedPackageVersions: linux-restricted-modules-3.13.0-83-generic N/A linux-backports-modules-3.13.0-83-generic N/A linux-firmware 1.127.20 + Tags: trusty + Uname: Linux 3.13.0-83-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: + _MarkForUpload: True + dmi.bios.date: 12/18/2014 + dmi.bios.vendor: Insyde Corp. + dmi.bios.version: V1.26 + dmi.board.asset.tag: Type2 - Board Asset Tag + dmi.board.name: BA50_HB + dmi.board.vendor: Acer + dmi.board.version: V1.26 + dmi.chassis.asset.tag: Chassis Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: Acer + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnInsydeCorp.:bvrV1.26:bd12/18/2014:svnAcer:pnExtensa2510:pvrV1.26:rvnAcer:rnBA50_HB:rvrV1.26:cvnAcer:ct10:cvrChassisVersion: + dmi.product.name: Extensa 2510 + dmi.product.version: V1.26 + dmi.sys.vendor: Acer ** Tags removed: dist-upgrade ** Tags added: bios-outdated-1.32 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1563491 Title: usb storage devices are no longer recognised by the kernel Status in linux package in Ubuntu: Incomplete Bug description: 1.
