[sane-devel] Problem with Brother DCP-7030 under Ubuntu 18.04

[Ulf Zibis]

Hi,

I have installed:
sudo add-apt-repository ppa:gunnarhj/sane-backends
sudo apt update
sudo apt install libsane1
sudo apt install sane-utils
brscan3-0.2.11-5.amd64.deb (installed from file manager with
double-click via Ubuntu Software GUI)
brscan-skey-0.2.4-1.amd64.deb (installed from file manager with
double-click via Ubuntu Software GUI)
sudo ln -sfr /usr/lib64/libbr* /usr/lib/x86_64-linux-gnu
sudo ln -sfr /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane
sudo -H gedit /etc/udev/rules.d/59-udev-local.rules with:
    # Brother brscan devices
    ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="*", MODE="0664",
GROUP="scanner", ENV{libsane_matched}="yes"

After restart of machine I get:
$ lsusb

$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

$ 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.

  # Your USB scanner was (probably) detected. It may or may not be
supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

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

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

Do you please have any hints, what to do more?

Thanks

-Ulf
