8BitDo Ultimate 2.4GHz wifi working in linux

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:

1. Create a new file /etc/udev/rules.d/99-8bitdo-xinput.rules
2. 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'"

3. Run the following command in a terminal: sudo udevadm control --reload
4. 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.

Thanks a lot! This worked for me. If the udev rule isn't working for you try changing the idProduct. 3106 did not work for me but 3016 did. Not sure why. dmesg showed several different idProduct numbers and 3106 was one of them.

Hello, can you explain step by step how to "Create a new file /etc/udev/rules.d/99-8bitdo-xinput.rules"? Thx.

# To create it
sudo touch /etc/udev/rules.d/99-8bitdo-xinput.rules
# To edit it (you can also use vim, gedit, whatever) 
sudo nano /etc/udev/rules.d/99-8bitdo-xinput.rules 

you just got me up and running, thanks!

Now I'm trying to see if there is a way to wake my pc with the 2.4Ghz USB on controller boot...

update to that wake venture, I got it working with these two articles (I had an issue with rc.local on debian 12 so the second article is for that):

Thank you, worked on my Powkiddy x55 running JELOS!

The original instructions work for me on Fedora 39, thank youi!! I was wondering if there was a way to get the paddles on the back working?

To the best of my understanding the paddles are programmed at the firmware level have to be assigned to another button or macro in the 8BitDo software. I loaded up the tool in a Windows VM, did USB passthrough with the controller, and wrote the firmware with the new assignments there. Once I saved it they worked back in my linux machine when connected as set.

Wow, that's very interesting!
Which mode are you using it in? The controller reports itself as 8BitDo Pro 2 Wired Controller in jstest with only 10 buttons
How does yours report itself?

EDIT: I just tried what @ammuench mentioned, set what I wanted to the paddles in a Windows VM, and now the paddles work as expected, as do the profiles / profile switching. Amazing stuff, thank you so much!

JFYI: it works out of the box on latest Linux Mint 21.3 with 6.5 kernel. Also it works out of the box on Steam Deck.

This was a big help, thanks!

Works out of the box in Fedora 40 now! I just bought the controller, plugged the 2.4GHz dongle in and it just works! also works via cable. Tho I only tested X input mode

Annoyingly the wireless dongle doesn't seem to have power/wakeup support, also, controller just doesn't work in general for me on Kernel 6.8

I concur. I'm having issues where sometimes Garuda Linux will see it connected, and sometimes it won't. The udev rule in this gist also didn't help fix it.

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.

1. create a /etc/udev/rules.d/99-8bitdo-xinput.rules with your favorite editor
2. inside the file, add the following:
   1. ACTION=="add", ATTRS{idVendor}=="2dc8", ATTRS{idProduct}=="3016", MODE="0666"
   2. This gives the input file of any 8bitdo controller R/W permissions automatically when connected.
3. reload udev with 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/)

FYI always check your model. the new ultimate 2.4ghz w/ the hall effect joysticks have id of 3109.

Yeah, I haven't actually been using any of the udev rules here, been writing my own. I updated to kernel 6.9.5 and haven't had any issues with the controller not working since, but still not seeing power/wakeup support. Wondering if they shipped the new hall effect ultimate controllers with a worse dongle.

cat "${${$(grep 3109 /sys/bus/usb/devices/*/idProduct):0:-5}/idProduct/power/wake}"
cat: /sys/bus/usb/devices/1-3/power/wake: No such file or directory

Certainly seems like they shipped the new ones with a crappier dongle, if this does turn out to be the case, they've definitely lost a customer in me, given they marketed this controller around the steam deck, knowing full well that the steam deck community wants a controller that can wake the system remotely.

I bought the Bluetooth/dongle version earlier this year, while the dongle is still causing problems with constant disconnects when using Bluetooth it works out of the box and can be tested with evtest.

I worked for me on Lubuntu 22.04 for the "8Bitdo Ultimate C 2.4g".
Thank you!

Just as described:

1️⃣ I ran: sudo nano /etc/udev/rules.d/99-8bitdo-xinput.rules and typed my computer password

2️⃣ I pasted the following line:
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'"

3️⃣ I pressed: CTRL + X

4️⃣ I typed "y" and then "ENTER" to save the buffer

5️⃣ I pressed "ENTER" one again

6️⃣ I ran: sudo udevadm control --reload

7️⃣ Disconnected the 2.4g receiver

8️⃣ Connected the 2.4g receiver

9️⃣ I pressed and held the "X button + 8bitdo button" in the controller until it did a small vibration

🔟 DONE!
