Steam Deck OLED "No device found"

[heavyelement]

Hi there.
I've tried running this application on my Steam Deck OLED and it doesn't seem to work. No matter if I run it with Steam open or closed, nor as root or not, the OLED's controller is not detected.

I've tried running this on my original Steam Deck as well, with the same results.

(deck@steamdeck Downloads)$ sudo ./steamcontrollersinger "Portal 2 - Want You Gone (rdvl97).mid"

No device found

Here's the (relevant) output of lsusb in case this is helpful

(deck@steamdeck Downloads)$ lsusb
Bus 003 Device 004: ID 28de:1205 Valve Software Steam Controller

Any idea on how I can get this working?

You can try this fork that claims to have Steam Deck compatibility.

Unfortunately, I don't have a Steam Deck. So I can not test it.
