Description Alex Markley 2019-10-11 21:48:43 UTC
Description of problem: Canon CanoScan LiDE 110 is no longer being detected or initialized by sane, affecting xsane, simple-scan, and others. This is a regression, previous versions interacted with the scanner no problem. Version-Release number of selected component (if applicable): sane-backends-1.0.28-1.fc30.x86_64 is the first version I noticed which exhibits the problem. sane-backends-1.0.27-23.fc30.x86_64 fixes the problem, and the scanner works as usual. How reproducible: 100% Steps to Reproduce: 1. Install `sane-backends-1.0.28-1.fc30.x86_64` 2. Run `sudo sane-find-scanner` 3. Observe `found USB scanner (vendor=0x04a9 [Canon], product=0x1909 [CanoScan], chip=GL124) at libusb:001:006` as expected in the output. 4. Run `scanimage -L` 5. Observe, no entry for the CanoScan. Actual results: `scanimage -L` produces no entries for the CanoScan LiDE 110, no sane-powered utilities can detect or interact with the scanner. Expected results: Normally `scanimage -L` produces the following for the CanoScan: device `genesys:libusb:001:007' is a Canon LiDE 110 flatbed scanner Additional info: Running `sudo dnf downgrade sane-backends` provides temporary relief from this problem.

Same problem with LIDE220. Bus 003 Device 008: ID 04a9:190f Canon, Inc. CanoScan LiDE 220 Downgrading to 1.0.27-24.fc30 fixes the issue.

Comment 3 Zdenek Dohnal 2019-10-14 12:42:09 UTC
Hi Alex and Philippe, thank you for reporting the issue! Actually it is caused by missing genesys backend as whole, who took care of this type of scanners. Genesys backend is now written in C++11 and it cannot be built without it due settings during configure phase. Buildroot did not have gcc-c++ during build and configure produced only warning about genesys will not be created. Adding gcc-c++ to buildrequires fixes it. Would you mind trying this build if it fixes it? https://koji.fedoraproject.org/koji/taskinfo?taskID=38290503

D'oh, the build failed, wait a minute...
Comment 5 Zdenek Dohnal 2019-10-14 13:16:08 UTC
x86_64 build is ok, so it is possible for you to test.
Comment 6 ced 2019-10-16 08:51:16 UTC
Hi, I had the same issue today (Canon LiDE 110 not detected with sane-backends-1.0.28-1 because of missing genesys driver). Using the build you linked to: Upgraded: sane-backends-1.0.28-2.fc30.x86_64 sane-backends-libs-1.0.28-2.fc30.x86_64 sane-backends-drivers-scanners-1.0.28-2.fc30.x86_64 genesys driver is back: ❯ locate genesys /etc/sane.d/genesys.conf /usr/lib64/sane/libsane-genesys.so /usr/lib64/sane/libsane-genesys.so.1 /usr/lib64/sane/libsane-genesys.so.1.0.28 /usr/share/man/man5/sane-genesys.5.gz And the scanner is detected: ❯ scanimage -L device `genesys:libusb:001:014' is a Canon LiDE 110 flatbed scanner But it crashes in xsane preview or scanimage test: ❯ scanimage --test Output format is not set, using pnm as a default. /usr/include/c++/9/bits/stl_vector.h:1042: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator(std::vector<_Tp, _Alloc>::size_type) [with _Tp = short unsigned int; _Alloc = std::allocator<short unsigned int>; std::vector<_Tp, _Alloc>::reference = short unsigned int&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n < this->size(), true)' failed.  19216 abort (core dumped) scanimage --test

Everything is ok with sane-backends-1.0.28-4.fc30 with lide 120. Thank you very much.
Comment 15 Kaarle Ritvanen 2019-10-21 21:28:38 UTC
Please fix this in Fedora 29 as well.
Comment 16 Zdenek Dohnal 2019-10-22 10:23:01 UTC
Kaarle, it is already fixed for F29, but the update is still in bodhi https://bodhi.fedoraproject.org/updates/FEDORA-2019-37c002492b with no karma - so it seems nobody wants to have it fixed fast. So there are two options: 1) you and two other people will add karma to the update and the fix will be in stable repos within days 2) you will install the fixed package by hand - either by enabling testing and installing sane-backends&friends, or get link to koji (which is in the update too) and install needed rpms by links.
