Canon have come back with: "Unfortunately you need to wait for scangearmp to update so that it then supports ubuntu version 14.04. We are not yet aware of a scheduled time of release for this update, the only thing I can recommend is that you keep an eye on the website to see when the scangear is updated to support this."
And I notice now at the download link for scangearmp v2.20 it says under System Requirements: Fedora 18(32bit/64bit) Ubuntu 13.04(32bit/64bit) So, maybe when Canon update scangearmp to support 14.04 they'll take a look at this bug... -- 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/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 Status in linux package in Ubuntu: Fix Released Bug description: 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. --- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1529232/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
