Troubleshooting

Device is not visible

If you don't see all of the devices that you expect to see, follow these steps:
    Make sure that you are connected to the Internet, so that Windows can download the necessary drivers
    Disconnect the device from the computer and then re-connect it
    Click the "Scan for Devices" link in the bottom-right corner of the Hardware tab
If that doesn't work, follow the steps for the type of device that is missing.

Control Hubs connected via USB

    Make sure that the Control Hub is plugged in via USB-C, not Mini USB
    Make sure the Control Hub has had a chance to finish starting up, and that its light is green
    Unplug the Control Hub from the computer and plug it back in

Control Hubs connected via WiFi

    Make sure that the Control Hub is running version 5.5 or later of the Robot Controller app
    Make sure the Control Hub has had a chance to finish starting up, and that its light is green
    Make sure that you are currently connected to the Control Hub's WiFi network
    Try rebooting the Control Hub. Re-connect to its WiFi network after its light turns green
    Plug the Control Hub in via USB instead

Expansion Hubs connected to a Control Hub

    Make sure that the Expansion Hub is in the active configuration file
    Make sure that the Control Hub is running version 5.5 or later of the Robot Controller app

Android phones

    Make sure that USB debugging is enabled in the Developer Options
      If you can't find Developer Options anywhere in the Settings app (it may be listed on a System screen or similar), make sure it is enabled by tapping on the Build number 7 times on the About screen of the Settings app.
    Unplug the phone from the computer and plug it back in. Look for a prompt to allow USB debugging, and click OK when it comes up.
    Make sure that the ADB driver for your Android phone is installed. For Motorola phones, do this by installing Motorola Device Manager.

SPARK MAX Motor Controller

    Make sure that the SPARK MAX is not being used by another application, such as the REV SPARK MAX Client
    Unplug the SPARK MAX from the computer and plug it back in
