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