FROM https://www.reddit.com/r/Fedora/comments/zmvkdj/8bitdo_ultimate_bluetooth_controller_working_in/
I've bought this new controller from 8BitDo and wished to use on linux, to my sadness the controller didn't work out of the box, neither by cable, the 2.4G dongle or bluetooth.
So I've tried a number of solutions and this one from u/GodOfEmus over in the 8bitdo community was the one to work for me:
- Create a new file /etc/udev/rules.d/99-8bitdo-xinput.rules
- Paste this udev rule in there, then save and exit the file:
ACTION=="add", ATTRS{idVendor}=="2dc8", ATTRS{idProduct}=="3106", RUN+="/sbin/modprobe xpad", RUN+="/bin/sh -c 'echo 2dc8 3106 > /sys/bus/usb/drivers/xpad/new_id'"
- Run the following command in a terminal:
sudo udevadm control --reload
- Unplug and replug the controller if it was already plugged in, it might take a second if you have the bluetooth version
It will basically "cheat" the OS to see the controller as an generic xbox device, so sadly no bluetooth nor gyro control if you care about that, but the rumbling is working for me.

For anyone who is looking to just make the controller work but not make it "cheat" the OS. You can use udev to give its input files read/write permissions.
/etc/udev/rules.d/99-8bitdo-xinput.rules
with your favorite editorACTION=="add", ATTRS{idVendor}=="2dc8", ATTRS{idProduct}=="3016", MODE="0666"
sudo udevadm control --reload-rules
or just reboot your computer.This is helpful when you want to just read the controller's input according to SDL, not remapping to an xbox controller. Example use case is when you want it to work with ROS (https://answers.ros.org/question/384456/ros2-joy_node-debugging/)
