Hi,
I've recently received my pre-order for a steam controller, but I can't seem to get it working. I plug in the USB adapter and it is identified, however I can't seem to connect the controller within steam. I did some research and apparently steam needs some extra read+write permission which can be handled via udev as per http://askubuntu.com/questions/686214/how-do-i-get-a-steam-controller-working. I've added this to services.udev.extraRules (adjusting the group as appropriate) and still no luck. I also tried changing permissions of uinput directly and I still have no luck. After further research I found nixos has had to jump through a few hoops to get steam to play nice by using chroot, which I suspect is the source of my problems but I am unsure how to proceed from here. Any ideas?

Thanks,
Adam

Notes

I do have steam working with a PS4 controller via a USB bluetooth adapter. However, the controller must be connected before steam starts as it is unable to pick up the controller dynamically.
