I have a #supernote manta, and I wanna use their app #inkflow, which supposedly turns the tablet into a graphic tablet (== input device).
I'm on nixos (a linux distro) and it just doesn't work.
Don't get me wrong: I can mount the device, I can use it as an ereader in calibre, so it is definetely connected.
Just the graphics tablet function doesn't work. The computer just doesn't react. The tablet thinks it is connected, afaict.
I already updated, and I turned off sideloading (this is required for inkflow for some reason).
My laptop recognizes normal wacom tablets, so it's not that all graphic tablets are broken or something.
any ideas? maybe i need some udevrules, that's at least what I expect.
