Note that it has
E: LIBFPRINT_DRIVER=Hardcoded whitelist
which is suspicious, why is libfprint touching that?
Furthermore, all devices attached to it have
ATTRS{power/control}=="auto"
in particular this causes problems for my mouse which doesn't like
being suspended - it takes a few seconds to wake up each time after I
stop using it, which is surprisingly annoying.
It's these rules:
SUBSYSTEM=="usb", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0002",
ATTRS{dev}=="*", TEST=="power/control", ATTR{power/control}="auto",
MODE="0660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0002",
ENV{LIBFPRINT_DRIVER}="Hardcoded whitelist"
which are matching, and they shouldn't be here since they aren't
matching a fingerprint reader.
This is listed on
https://gitlab.freedesktop.org/libfprint/wiki/-/wikis/Unsupported%20Devices
as being "Mantra MFS100", which seems wrong I think.
