Verbose output -verbose of Moonlight Embedded:
N/A

What is the expected result?
moonlight map -input /dev/input/by-id/usb-Valve_Software_Wired_Controller-if01-event-joystick to react to triggers pulled on Steam Controller. Nothing happens.
What happens instead of that?
Only buttons at the end of the trigger pull are recognised.

jstest can read the analog triggers fine, and it seems like someone else has mapped the analog output to the triggers(ID 03000000de2800004211000011010000), which means it should work in other software (I guess?).

I have found this as a potential cause, but the code in evdev.c goes way over my head. I understand that the Steam Controller is rather niche, so I don't expect a fix, but happy to test anything that might fix it!

By the way, this software is incredible, I've got it running with VAAPI, 1080p120 and it's virtually indistinguishable from sitting at my desk. Made playing in the living room possible, so thank you so much!
