I did exactly what I've done several times in the past: download the
RPM and run 'dnf install ...". This has always worked.
However on closer inspection I see this from the configure tool:
# brsaneconfig4 -a name=Brother model=DCP-7055W ip=192.168.1.4
# brsaneconfig4 -d
[...]
sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the

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).

Note that it's searching in /proc/bus rather than /sys/bus, which may
be wrong. However AFAIK this hasn't changed since I've been using it
and in any case shouldn't matter as it's not connected via USB.
