- If you see the icon, mouse over it to check if the firmware is out of date. If so, click Update controller firmware.
- Using a micro-USB cable, connect the controllers to one of your computer's USB ports one at time.
Once the controller is detected by the SteamVR app, the firmware update will start automatically.Warning: Do not unplug the micro-USB cable any time before the firmware update is complete. Doing so could result in a firmware error.
- When the update is complete, click Done.
