I'm seeing the same thing, the controller works fine in none steam games, but as soon as I start steam it vibrates like crazy.
udevadm info for 8bitdo sn30 pro usb
dmesg when connecting 8bitdo sn30 pro
I'm running ArchLinux with steam built Nov 22 2021, at 22:12:42.
I have tried:
You don't understand how your controller works.
hid-nintendo (or hidraw if on kernel 5.15 or lower) only works when the gamepad is powered on via Start + Y.
xpad is used when the gamepad is powered on via Start + X.
Blacklisting xpad is a poor decision, because no xbox pads will work, including your SN30 Pro in that mode.
Connecting it to a a computer with kernel 5.15 or lower will work, as hidraw is loaded and steam's /lib/udev/rules.d/60-steam-input.rules makes the controller work. This is probably why your friend's computer is working.
You need to blacklist hid-nintendo until Steam fixes their 60-steam-input.rules file to reflect newer kernels, and initialize your SN30 using Start + Y.
Ok, blacklisting hid_nintendo and as this is a wired USB controller, holding Y and plugging the controller in, makes it show up as:
Bus 001 Device 009: ID 057e:2009 Nintendo Co., Ltd Switch Pro Controller
The controller now "works" in Steam and Stardew Vally - but only the d-pad and buttons, analog sticks do not.
Holding X and plugging the controller in, makes it show up as
Bus 001 Device 010: ID 045e:028e Microsoft Corp. Xbox360 Controller
And it also works in games.
Just plugging it in without holding any buttons also makes it show up as a Xbox360 controller, except when starting Steam or Stardew Valley it goes into that crazy disconnect/connect, nintendo switch/xbox fubar :)
The manual does not state this (https://download.8bitdo.com/Manual/Controller/SN30pro-USB/SN30-Pro-USB.pdf) and there is no print on the bottom of the controller as there is on the bluetooth version.
@jason-oliveira thanks for the input, holding X and plugging in is a ok workaround for now :)
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
While the controller works in other games/applications, it does not work in Steam.
When I go in the controller settings in Steam Big Picture, I see the controller appears sometimes as a Nintendo Switch Pro and then disappears. Sometimes, it also appears as an Xbox controller, but it also disappears after 1 second.
Here are the console logs of Steam.
It shows that the controller gets disconnected.
udevadm monitorwill show stuff happening when Steam starts.I tried many things like adding some udev rule:
(I also tried with values adjusted for the my 8BitDo controller.)
I tried hid-nintendo-dkms and game-devices-udev.
I tried blacklisting the Switch "device" of my controller, but Steam logs would show:
The weird thing is that I get this issue on all my computers (different ThinkPads and a desktop) but I don't get it on my friends' computers (using my Steam account or theirs). Using their Steam account on my computer don't fix the issue.
Also weird, I am sometimes able to have the controller working in Steam: the last time, it was by creating a new Linux account on my computer. But it stopped working and I can't make it work again this way.
