Steam Controller 2026 and Seeed Studio Xiao nRF52840

[Sebiann]

I'm trying to connect my Steam Controller using bluetooth.

I installed hid remapper on my Xiao nRF52840 and it can connect the steam controller, but only the dpad, A, B and the 2 Touchpads are detected. It doesn't seem to detect any other inputs

Because of the non-standard way the Steam Controller reports its inputs, it needs some additional handling. This can be done either through quirks built into the firmware or through custom usages. We have quirks for a wired Steam Controller, but they're not currently be used for Bluetooth because we're not reading VID/PID for Bluetooth devices (for no big reason, I just never got around to implementing it).

You can try getting the inputs through custom usages. All the necessary information is here:
