Nintendo Switch 2 Pro Controller Does Not Work (Linux) SDL 3.4.2

[theofficialgman]

After reading the release notes, I expected everything to work out of the box for Nintendo Switch 2 Pro Controllers, however I have found that to be anything but the case.

Compiled SDL 3.4.2 from source with testcontroller, see the output (no stick movement or button actions and lights constantly flash left/right at the top):

~/SDL/build/test$ ./testcontroller

this is after having already added

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="2069", MODE="0660", TAG+="uaccess"

as a udev rule, reloading, and rebooting.

for reference, kernel logs from plugging in the device over USB

running with sudo does work, so something is wrong with the udev rule which was suggested by SDL developers

~/SDL/build/test$ sudo ./testcontroller
