[sane-devel] Brother DCP 7030 scanner on Ubuntu 18.04 – please help

[Ulf Zibis]

Hi Thierry,

thanks again for your effort.

The scanner still doesn't work.

What should I enter for the nodename here? :
> brsaneconfig3 -a name=DCP7030 model=DCP-7030 nodename=BRN_xxxxx

Here my new output:

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).
jannis at MS-7616:~$ brsaneconfig3 -a name=DCP7030 model=DCP-7030
nodename=libusb:001:004
"DCP7030" is already registered.

  # 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.
