So often connected devices have to be “overriden” again within Wine too.

There are now still 2 entries for the same Model and Vendor id in the Wine reg. One for xinput. And this is e.g. prioritized by some games like Elite so they will only start to listen on xinput here, where nothing ever arrives. In that case references to xinput have to be removed again from the registry. Only to be auto repopulated by the next Proton upgrade in some cases or when the device enumeration changes for some reason. Pain.
