Comment 7 for bug 1498658

As reported by stephen, it has been noted there is a typo in the udev rules.

On a fresh 15.10 install, changing

SUBSYSTEM=="usb", ATTRS{idVendor}=="28de", ATTRS{idVendor}=="1102", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="28de", ATTRS{idVendor}=="1142", MODE="0666"

to
SUBSYSTEM=="usb", ATTRS{idVendor}=="28de", ATTRS{idProduct}=="1102", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="28de", ATTRS{idProduct}=="1142", MODE="0666"

fixes the issue.

Please release commit a new fix. I was quite surprise that the steam controller issue is not fixed already.
