Valve has already sent support for the new Steam Controller upstream: https://www.phoronix.com/news/New-Steam-Controller-SDL
The first controller looked the same, but was very good to use once you got used to it. The build quality, though, was...fucking terrible.
I had to fix my controllers so many times that in the end I was swapping them out almost weekly. Still, felt great in the hand.
It might be you just got unlucky. Mine is still going strong all this years, and I use it often.
I have the first controller, just dug it out the other day because I thought I was going to be able to use it on my new tablet, it still sucks. I never could get used to it, but it's a far sight better looking then this thing.
