Most likely reason is either the software is not installed, or the hardware
needs a udev rule.

On my Mageia 9 system ...
# rpm -q -f /usr/lib/udev/rules.d/60-libsane.rules
sane-backends-1.1.1-4.mga9

Assuming the various "sane" packages have been installed, copy the above
file to "/etc/udev/rules.d/" and add an entry in the /etc copy such as

ATTR{idVendor}=="1e4f", ATTR{idProduct}=="2401", MODE="0644", GROUP="usb", ENV{libsane_matched}="yes"

Then reboot or run "udevadm control --reload-rules && udevadm trigger" (as root).
