When I run remouse with --evdev, it crashes after Debugging enabled...:

I'm on Ubuntu 18.04; is this just "your system libevdev is too old"?

I'm not sure, but its failing at importing libevdev, so it's not a problem here.

On Debian 11:

[evan@blackbox ~] readelf -Ws /usr/lib/x86_64-linux-gnu/libevdev.so.2 | grep libevdev_event_value_get_name

ugh, ok, yeah; I have libevdev 1.5.8, but libevdev_event_value_get_name was added in 1.6.0: https://lists.freedesktop.org/archives/input-tools/2018-October/001488.html
