Connect your Altura using its original USB cable.

FIRST TIME HERE? First-time setup · Windows

Altura not listed when you click Connect? Check the USB cable, then run setup if this is your first time on this computer.

The easy installer is being prepared. Manual driver download ↗

First-time setup only — if Altura connects, you’re ready. Open the installer, approve the Windows prompt, then accept the Silicon Labs licence and choose Install driver. Internet access is required.

Need more help?

Use Chrome or Edge on Windows and the original Altura USB cable. Close other apps using Altura before connecting.

Manual driver installation: download the Silicon Labs CP210x Universal Windows Driver ZIP, select Extract all, then right-click silabser.inf (Setup Information) in the extracted folder and select Install. On Windows 11, select Show more options if needed. Return here and try connecting again.

Altura is listed but does not respond?

Windows may have assigned the same COM number to Altura and an old device. Open Device Manager → View → Show hidden devices → Ports (COM & LPT). If two entries use the same COM number, open the connected Silicon Labs CP210x device → Properties → Port Settings → Advanced, then choose an unused number such as COM7. Unplug and reconnect Altura before trying again.

Remove only a greyed-out duplicate you recognise. Do not remove unrelated Bluetooth, motherboard or business devices.

On a work or school computer, ask IT if USB access or installation is blocked.

A LITTLE GUIDANCE

Good to know.

Do I need to install a driver every time?

No. If Silicon Labs CP210x appears in the connection picker, select it. Install the driver only when needed; you normally do this once per computer.

Why can’t I see Altura?

Check the USB cable and port, close other apps or tabs using Altura, then try again. If the device is still missing on Windows, follow the CP210x driver steps above. A work or school computer may need permission from IT.

Altura appears, but says it is not responding

This can happen when Windows has a stale or duplicate COM-port assignment. It does not prove that Altura needs a firmware update. Disconnect, try the other CP210x entry if one appears, or follow the Windows COM-port steps in First-time setup.

Can I control Altura from my phone browser?

This page is designed for USB control in desktop Chrome or Edge on Windows. Mobile app links will appear above when available.

Will connecting change my lighting?

Connecting checks the device first. Select a colour, mode or brightness control when you want to make a change. Saved browser preferences are not proof of the device’s current state.

How do firmware updates work?

The controller checks compatibility after connecting and shows an update option when required. Start the update yourself, keep Altura connected and leave this tab open until it finishes.

Are all effects ready to use?

Audio Sync is a beta feature. Screen Sync remains under development and is unavailable in the customer controls.
