[SOLVED] Brother DS-620 scanner is not recognized

jolivier · 2019-10-18 15:48:16

I am trying to use my Brother DS-620. I found and installed https://aur.archlinux.org/packages/libsane-dsseries/ , but I can't get my scanner to be recognized.

 sudo sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

Although lsusb sees my scanner:

The other people having the same issues fixed it by enabling the 'sg' module but this didn't fix it for me:

lsmod | grep sg
sg                     40960  0
ipmi_msghandler        69632  2 ipmi_devintf,nvidia
scsi_mod              249856  5 sd_mod,usb_storage,uas,libata,sg

The scanner is listed as a disk:

lsscsi -g

I tried to test the udev rule added by the package (based on https://superuser.com/a/1392450) but it seems that it is not fired by this device:

udevadm info --name /dev/sg5 --query all
P: /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.0/host6/target6:0:0/6:0:0:0/scsi_generic/sg5

dmesg when I plug in my scanner is:

The only notable thing that might have an impact for me is that I tried all other brother scanner driver packages before this one. I uninstalled them so normally this shouldn't have any consequence.
The driver package indicates the user should be in the 'scanner' group so I added myself in this group but cannot still access the device, what is strange is that the udev rule from the driver is

KERNEL=="sg[0-9]*", ATTRS{type}=="0", ATTRS{vendor}=="Brother", ATTRS{model}=="DS-620", MODE="0666", GROUP="users"

Which for me means that it gives access to the users in the 'users' group to this device, not the 'scanner' group. And from my test above it seems that this rule isn't event triggered.

What should I do investigate further / fix this ?

Thanks,
Olivier

You did try the sane verification steps ?

The output of scanimage --list-devices may also be useful.

NOTE : run as normal user please, not sudo or root .
If the commands fail as user, post logs/output and investigate why they fail.

Thanks, while investigating again why the commands fail as a normal user I tried to reload the udev rules with

udevadm control --reload

and

udevadm trigger

and afterwards my scanner was detected, the udev rule was working and everything is fine !
So I'm not sure exactly what was the issue I will have to retry after a reboot if the problem persists. For other that have the same problem I recommend the udev rules reload commands above, I didn't do anything else to have it working ( which makes no sense to me since I tried anyway to reboot with the new rules so udev should have picked them, even if inotify was not working).
I'll mark this as solved since I don't need help anymore but I'm not satisfied with the solution and might comment later.
