[Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Lucas Partridge, at your earliest convenience, could you please test the
latest upstream kernel available from the very top line at the top of
the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
(the release names are irrelevant for testing, and please do not test
the daily folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel 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 issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
Scanner not detected over wifi since after 3.13.0-68
Status in linux package in Ubuntu:
Incomplete
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.
