Hello!

I've just set up Steam Link on my x86 Linux machine (Arch) and it loads up just fine but no button presses on my controllers are recognized.

I tried both an Xbox 360 Wired Controller and an Xbox One Wireless Controller (plugged in via USB).

I got past the initial setup by plugging in a keyboard and using that to connect Steam Link to my home PC with Steam on it.

• Both controllers are recognized by Steam Link (green checkmark)
  
• Both controllers are recognized by Linux
  
• The controllers are accessible by the user running Steam Link. I verified this by running "cat /dev/input/js0" and I could see output every time I pressed buttons
  
• On the launch screen of Steam Link, no button presses register. I can press all buttons, but nothing happens. Using a keyboard, I made it past this screen into Big Picture, but no buttons were recognized there as well.
  
• I tried both the flatpak version as well as directly running on my system, both versions have the same issue
  
• The log output of Steam Link says that it found my controller and displays its button mapping.

I am running out of ideas on how to debug this further. Anyone got any ideas?
