** Description changed: Please see http://ubuntuforums.org/showthread.php?t=2306464 for details. I'm running 64-bit 14.04 LTS ubuntu. When I boot my PC into 3.13.0-68-generic (via the 'ubuntu advanced' menu item in grub) I can detect my scanner over wifi using scangearmp. However since 3.13.0-70-generic I have not been able to detect my scanner over wifi. My current kernel is 3.13.0-74-generic. Therefore I suspect a regression has occurred between 3.13.0-68-generic and 3.13.0-70-generic: Scanner *is* detected by scangearmp over wifi and it scans documents as expected in this version: uname -a Linux zorro 3.13.0-68-generic #111-Ubuntu SMP Fri Nov 6 18:17:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux But scanner is *not* detected by scangearmp in this version or later: Linux zorro 3.13.0-70-generic #113-Ubuntu SMP Mon Nov 16 18:34:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Note that this happened before some time ago. i.e., The scanner was detected over wifi, then not, then it was again some time later. Then this latest break occurred again. I suspect successive updates are fixing or breaking the detection accordingly. $ dpkg -l | grep scangear ii scangearmp-common 2.20-1 amd64 ScanGear MP for Linux. ii scangearmp-mg7100series 2.20-1 amd64 ScanGear MP for Linux. Device is Canon Pixma MG7150 (combined printer, scanner, copier). Note the printer works fine over wifi; only the scanner is affected. - I can see from the changelog at - http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_3.13.0-74.118/changelog - that many changes went into 3.13.0-69.112 but it's not obvious to me - which of these might have caused the regression. + I can see from the changelog at http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_3.13.0-74.118/changelog that many changes went into 3.13.0-69.112 but it's not obvious to me which of these might have caused the regression. + --- + ApportVersion: 2.14.1-0ubuntu3.19 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: lucas 1604 F.... pulseaudio + /dev/snd/controlC2: lucas 1604 F.... pulseaudio + /dev/snd/controlC0: lucas 1604 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=0140e677-b732-4571-a80a-fc5d7c00359c + InstallationDate: Installed on 2014-12-05 (387 days ago) + InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) + MachineType: MICRO-STAR INTERNATIONAL CO.,LTD MS-7528 + NonfreeKernelModules: nvidia + Package: linux (not installed) + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-74-generic root=UUID=941f5e44-f02e-42f2-ac78-5f6b4b9e98e9 ro quiet splash + ProcVersionSignature: Ubuntu 3.13.0-74.118-generic 3.13.11-ckt30 + RelatedPackageVersions: + linux-restricted-modules-3.13.0-74-generic N/A + linux-backports-modules-3.13.0-74-generic N/A + linux-firmware 1.127.19 + RfKill: + 0: phy0: Wireless LAN + Soft blocked: no + Hard blocked: no + Tags: trusty + Uname: Linux 3.13.0-74-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 06/19/2009 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: V1.3 + dmi.board.asset.tag: To Be Filled By O.E.M. + dmi.board.name: G31M3-F(MS-7528) + dmi.board.vendor: MICRO-STAR INTERNATIONAL CO.,LTD + dmi.board.version: 1.0 + dmi.chassis.asset.tag: To Be Filled By O.E.M. + dmi.chassis.type: 3 + dmi.chassis.vendor: MICRO-STAR INTERNATIONAL CO.,LTD + dmi.chassis.version: 1.0 + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrV1.3:bd06/19/2009:svnMICRO-STARINTERNATIONALCO.,LTD:pnMS-7528:pvr1.0:rvnMICRO-STARINTERNATIONALCO.,LTD:rnG31M3-F(MS-7528):rvr1.0:cvnMICRO-STARINTERNATIONALCO.,LTD:ct3:cvr1.0: + dmi.product.name: MS-7528 + dmi.product.version: 1.0 + dmi.sys.vendor: MICRO-STAR INTERNATIONAL CO.,LTD ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1529232/+attachment/4540973/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1529232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
