redirecting my steamdeck control via usb to my linux gaming rig and expose it as a usb device(s) for steaminput.
It seems like a natural and perhaps even "straightforward" hack but I've seen no evidence of one so far, perhaps there is something in usb that limits the ability to proxy it correctly.
If so... while searching to see if the SD supports gadget mode (answer: yes) I happened across https://github.com/Frederic98/GadgetDeck - have you tried that?
From what I can discern its missing important bits of the controller and doesn't have any steaminput profile etc so it's clunky still.
Worth poking at though.
edit - to clarify, ideally steaminput would be tricked on the host to think that it "was" a steamdeck so all the mapping features would be available. I don't really need another usb game controller its more the steamdeck touchpad etc.
Even a bluetooth mouse has too much latency for many games.
That rtings graph shows that bluetooth is pretty clearly worse in the majority of cases from wired or wireless (which is distinct from bluetooth).
"Bluetooth" doesn't appear anywhere on that Reddit thread.
And from the second rtings:
> The mouse's connection type affects the click latency. Generally, wired mice have the lowest latency, and Bluetooth mice have the highest latency. A Bluetooth connection isn't recommended for gaming, but it's still good for office use, and most people won't notice any delay unless the latency is extremely high.
Click latency is not too useful vs swipe latency.
Bluetooth has a pretty low polling rate iirc and that kills the swipe latency.
More generally and responsive to what we were talking about, proprietary radios are not bluetooth and they are not WiFi which is the latency we are actually talking about (which is usable but not for me to play elden ring by direct experience).
All the mice I am aware of that use Bluetooth are travel mice and the like. Even cheap gaming mice use RF dongles that do not have the Bluetooth polling limitations.
You can tell your friends in Fortnite you died because of mouse latency, but lets keep HN discussions grounded in reality please.
And AFAIU that would enable proxying of USB devices.
edit; oh nm, user wants a direct wired connection to work.
That would depend on the USB hardware on the device, I think.
