First controller driver release

Controls are being mapped correctly.

Known Bugs

• Steam still produces controller inputs even if we are hooking the hid device. Therefore with the driver active you will get doubled inputs in BigPicture mode and steam games.
• The driver sometimes fails to grab the serial number / fails to initialize. Make sure steam is closed when launching the driver. If that doesnt help, reboot.
