I had this problem trying to connect my new PS4 controller. Kept clicking submit and my preferences would not save.

And then I clicked “cancel” instead of submit … and it worked.

Hopefully this works for everyone else too

I've had this with the Steam Controller too. I wish I'd noticed when it fixed itself but eventually I was able to edit again. I just gave up in the short term.

I had that same problem a while back (twice actually), not just with my Steam controller but also XB360. Eventually I just waited for a Steam update and it suddenly worked.

One thing that helped, I was able to load an older config, edit and export as a new one, and I was only able to do this on my second computer (laptop) to get it to save and work properly across both PCs. That obviously only works on a game with existing profiles so I was SOL on some games until the update, and I can't say that would still work now.

Im unable to change the controller name and led brightness, not the in-game configs itself, i usualy use the backup config trick for that.

Thanks for the replys tho :)

welp it wont work for me :(

I'm trying to set up a X 52 Pro hotas to work properly with No Man's Sky. I followed a steam guide on using the controller settings to map some of its buttons to xbox buttons that the game will recognize. After playing around with it for a few days, I've realized that I need to change it so that different buttons are being used for things. However steam won't save it everytime I try to remap it.

The fact that they still haven't fixed this is embarassing

Big time, Microsoft don't care, clearly. I never had this issue even ONCE on Linux.
