The SF30/SN30 pro support 4 different modes:
* Switch mode (START + Y)
This looks like a nintendo switch pro controller
* Xinput mode (START + X)
This looks like an XBOX 360 controller
* Dinput mode (START + B)
This looks like a more generic gamepad
* macOS mode (START + A)
This looks like a Sony DS4 controller
3 modes have had a difficult time enumerating in fwupd.
Switch mode:
* failed to add USB device: unexpected device response
Xinput mode:
* failed to add USB device: USB error on device 045e:028e : Pipe error [-9]
macOS mode:
* failed to add USB device: failed to send to device on ep 0x01: USB error on device 054c:05c4 : Input/output error [-1]
The only mode I've gotten a nearly full update flow working is Dinput
so far. After updating the controller comes back in switch mode.
This means we can trivially support new devices in the future without compiling
any new code. This makes it easier to add support for new hardware for LTS
distros like RHEL.
