## What works

Almost all the hardware works after configuring drivers, including

- WiFi
- Bluetooth
- Touchpad
- Webcam

## What does not work

The fingerprint reader (`0a5c:5834`) is not supported because no linux driver exists so far (Sep 2017).

The IR camera can be used to take a picture but not for log in at the moment.
