So how do you update firmware with just a Steamdeck? 8bitdo does not seem to supply Linux software support anymore, so it feels a bit hilarious that they support SteamOS without any official way of updating controllers there.
I found the fwupd tool on github, but it seems a hacky way that cannot update everything. Can the 8bitdo tool be run via proton/wine?
Isn't fwupd already included in SteamOS? Or is there a specific 8bitdo fwupd tool?
maybe it is (don't have my deck with me to check) but even so, it is not an officially supported tool and I can see from issues on Github that people cannot find their controllers on there. not sure if that's very old or very new ones.

In the devices list of lvfs/fwupd there's a bunch of controllers supported. But it seems like it's mostly their retro controllers. XBox-style controllers like their Ultimate C etc. are not supported.
Tried it, not it cannot
