### **3. Install udev rules**

See: https://www.reddit.com/r/Stadia/comments/egcvpq/comment/fc5s7qm/
On Linux, Nintendo Switch controllers are often exposed as read-only `hidraw` devices.
When this happens, applications can detect the controller but cannot send initialization or rumble commands.

Adding udev rules allows user-space applications to write to the controller device,
which is required for proper initialization and haptics.

After installing the rules below, disconnect and reconnect the controller.
If Steam is installed, similar rules may already exist and this step may be unnecessary.

```bash
cat << 'EOF' > /etc/udev/rules.d/50-nintendo-switch.rules
