IMO, we should prepare the plumbing for those "dials" to be capable of handling direct/indirect, but we might not want to switch the existing indirect ones right now as users might lose functionality if they are not using wayland. As for the Dell one, it is currently ignored by the kernel, so we can simply do the right thing right now and not care about the existing stack. > >> (About 200 units of currency) >> >> As well as 2 devices from 3D Connexion: >> https://www.amazon.fr/dp/B000LB7G00/ >> https://www.amazon.fr/dp/B00283VWK4/ > > I have an old version of the second one floating around.

These are 3D mouse that report RX/RY/RZ and DX/DY/DZ. They are already handled properly (let's hope) by blender or the tools they are supposed to work with, and we probably do not want to break those. The main difference between the Dell Totem (or the Surface Dial) is in the purpose: it is aimed at showing a menu (related to the app or not) and navigating through it.
