@wmarler first of all thanks to your work.
I encountered an issue when using the command make. So when I try to use the commands
make -C /lib/modules/uname -r/build/ M=$(pwd)
$ sudo make -C /lib/modules/uname -r/build/ M=$(pwd) modules_install
its something like :
make : Entering directory ........
make : *** No rule to make target ´ /build/´ . Stop
make : Leaving directory ´ /lib/modules .......

I am quite new to linux on that level so I dont know what to do. Has somebody an idea.

It may have changed something because when I try to plug in the keyboard after starting the game with it unplugged, the keyboard doesn't do anything.

I saw someone using sc-controller in a youtube video so you can try that

@bengdahl Did you ever find a solution for this? I'm having the exact same problem.

Now, yes

But installed, going to configure input, same thing...

Reboot, an try again, same result :(

Edit: Try in xbox360 mode, and desktop mode... same results

Hi, did you have any luck with getting the Steam controller to work?

ok, after 2 days, I finally solved the problem..by default steam stores, the file /lib/udev/rules.d/99-steam-controller-perms.rules

for some reason the retropie script also installs /ect/udev/rules.d/99-steam-controller-perms.rules

the file in /ect contained the instructions for xbox and keyboard which was overridding the /lib rules.
I removed the ect file which should not be there and everything is now working. (I actually removed both files and reinstalled steam-devices)
