map2 VS logiops

https://github.com/shiro/map2 - another neat remapper program. more complex and no gui but more scriptable

I've also used a remapper tool called map2 but for a different use-case. Map2 documentation links to some of the scan codes though which could be helpful if you end up having to map the function keys to something... not really sure how those work but I've used it to map multimedia keys on a logitech k400 htpc keyboard before.

Maybe map2 can do some things you need.

As a temporary workaround and probably a long shot: but if not hw related and you are getting the keypresses but they're being ignored... maybe you could get away with some keyboard remapping apps? Maybe map2 or kbct

A linux alternative to AHK I made called map2 lets you do that easily, although there are other remapping projects as well.

for number 3: One way to bind mouse (keyboard, controller, etc.) keys similar to AHK is map2. It's significantly easier to use than Xorg keybindings and lets you do application specific bindings. Your can bind keys, key sequences and even complex actions such as scripts.

I'm the author of map2 that lets you map keys to other keys, sequences and complex actions like running a script. I haven't tried it with wiimotes (but I will when I find some time) so one would have to inspect which key events are emitted in order to remap them.

I'm the author of map2 which allows you to write simple scripts to remap buttons (incl. mouse), also you can do so per application. It's very flexible, but might require some programming skills, I recommend reading the docs and check the examples folder (there is a logitech mouse example too).

Mapping thorough X11 might not work everywhere and it's clunky. I'm the author of map2, it lets you do AHK-style key remapping and scripting on evdev level (meaning it's below X11 or wayland), so it works everywhere.

I've used both a Master 3 and a 3S, and have generally found that you need the logiops driver for full support. I'm not sure about its compatibility with Blender OOTB, but it gives you full HID control over the mouse via a config file.

Assuming you are comfortable with a little bit of scripting, there is a program called logiops - https://github.com/PixlOne/logiops that I use. With this I can control all the gestures and remap them into anything I want. For instance right now if I hold the gesture button and move the mouse back it will act as alt tab. If I move it left or right, it changes my tag/workspace (awesomewm). And so on.

Looking into it some more, there's logiops: https://github.com/PixlOne/logiops
