Hi Luca, In your diff.sane.txt I've found these two entries (problem seems related to settings of c189:130) :
< openat(AT_FDCWD, "/run/udev/data/c189:130", O_RDONLY|O_CLOEXEC) = 33 < fstat(33, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0 < fstat(33, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0 < read(33, "I:4009030\nE:ID_VENDOR=Brother\nE:"..., 4096) = 670 < read(33, "", 4096) = 0 < close(33) = 0 < getrandom("\213%[2\301\372\rH\260\347\r\2\374\2340\344", 16, GRND_NONBLOCK) = 16 --- > openat(AT_FDCWD, "/run/udev/data/c189:130", O_RDONLY|O_CLOEXEC) = 411 > fstat(411, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0 > fstat(411, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0 > read(411, "I:4009030\nE:ID_VENDOR=Brother\nE:"..., 4096) = 670 > read(411, "", 4096) = 0 > close(411) = 0 > getrandom("\"\215\241\234r\351\310\233\25\f\\\374`\3304N", 16, GRND_NONBLOCK) > = 16 So next step would be: 1. 'sane-find-scanner' last time you did this output was 'found USB scanner (vendor=0x04f9 [Brother], product=0x035d [MFC-1910W]) at libusb:002:006' But please run it again for being sure, usb port could have changed... 2. 'udevadm info -a /dev/bus/usb/002/006' (/002/006 has to be replaced by output of 1.) Post result here (Complete device please. Looks like: looking at device '/devices/pci0000:00/0000:00:14.0/usb3/3-3', parent devices are of no interest) 3. 'udevadm test /devices/pci0000:00/0000:00:14.0/usb3/3-3' (/devices/pci0000:00/0000:00:14.0/usb3/3-3 has to be replaced by output of 2.) Post result here (Complete please. For interest are lines like : handling device node '/dev/bus/usb/003/004', devnum=c189:259, mode=0664, uid=0, gid=0 preserve permissions /dev/bus/usb/003/004, 020664, uid=0, gid=0 preserve already existing symlink '/dev/char/189:259' to '../bus/usb/003/004') Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728012 Title: Many 3rd party scanner drivers are broken by a sane change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
