Step 1: Basic Troubleshooting (Solves Most Cases)

1. Check the Physical Connection (Most Important)

Reconnect the USB Cable

Unplug the StreamDock from your computer, wait a few seconds, and plug it back in. Make sure the USB cable is fully inserted and securely connected on both ends.

Try a Different USB Port

Test different USB ports on your computer, especially the rear motherboard USB 3.0 ports on desktop PCs. Avoid using USB hubs, docking stations, or front-panel USB ports whenever possible.

Try a Different USB Data Cable

Some USB-C cables only support charging and do not support data transmission. We recommend using the original StreamDock cable or another high-quality USB-C cable that supports both charging and data transfer to rule out cable-related issues.

2. Check the StreamDock Device

Screen Status

After connecting the device, check whether the screen lights up.

If the screen is on but the computer does not respond, make sure the MiraBox software is running.
If the screen does not turn on at all, the issue may be related to power delivery or hardware.

Test Device Functionality

Once the screen is on, press several keys and verify that the display responds normally. For example, check whether the screen can switch between active and sleep states.

Restart Your Computer

A simple restart can often resolve temporary driver conflicts or system-related issues.

Step 2: Software & Driver Troubleshooting

If the basic checks above do not solve the issue, the problem may be related to software, drivers, or operating system permissions.

1. Check the MiraBox Software

Run as Administrator (Windows)

Right-click the MiraBox software icon and select Run as Administrator.

Reinstall the Software

Uninstall the current version of the MiraBox software.
Restart your computer.
Download and install the latest version from the official MiraBox website.

Check Software Settings

Make sure features such as "Simulation Mode" or other special device modes are disabled if they may interfere with normal device communication.

2. Check System Permissions (Common on macOS)

When connecting a MiraBox StreamDock on macOS, the system may display a prompt asking for permission to access input devices.

Be sure to click Allow.

If you accidentally denied the request or never received the prompt:

Open System Settings
Navigate to Privacy & Security
Select Accessibility
Locate MiraBox in the application list
Ensure the permission is enabled

If necessary, click the lock icon to make changes and grant the required permissions.

Step 3: Contact MiraBox Technical Support

If the issue persists after completing all troubleshooting steps, please contact the MiraBox support team.

When submitting a support request, please provide:

Your StreamDock model
Your operating system version (Windows 10, Windows 11, macOS, etc.)
A description of the issue
The troubleshooting steps you have already attempted
Screenshots of Device Manager (Windows) if applicable
