USB Mobile Monitor

Installing and Using the USB Mobile Monitor

PC Installation

Device drivers are required to connect your PC to your Android device. Follow these steps to install the device drivers:

  1. Connect your device to the PC using a standard USB cable. If your PC is configured to automatically install device drivers and this is the first time you connect the device, Windows will start installing the default device drivers for the device. Allow the device driver installation to finish before going forward. If your PC is configured not to automatically install device drivers, proceed to the next step right away.
  2. Download the USB Mobile Monitor installation package
  3. When asked to Open or Save, click on Open
  4. Inside the compressed, you will find usbmmInst.exe, double-click on that file to start the Installation
  5. Follow the installation instructions. The screen will flicker during the installation of the drivers which is normal.
  6. The installer will ask you to unplug the device and plug-it back again, please do so.
  7. Click on Close to finish the installation. If the Android App is already installed on the device, your PC screen will appear on the device, if not proceed to the device installation step.
  8. On some occasions, MS Windows might overwrite the USB Mobile Monitor drivers with the device specific drivers. In this case, the PC screen will not show up on the device and it is sufficient to restart the installation process from step 2 without uninstalling the device drivers. You should also repeat the same installation steps when USB Mobile Monitor is used on the same PC but with a new device.
  9. To uninstall the USB Mobile Monitor, go to the control panel, programs and features, select USB Mobile Monitor and click uninstall. Alternatively, you can run Uninstall.exe directly from c:\users\[your user name]\AppData\Local\USB Mobile Monitor.
  10. To update to a newer version, always uninstall USB Mobile Monitor first, reboot your system (optional but recommended), then reinstall the new version of the PC drivers.

Device Installation and operation

The device installation can be done before or after the PC installation by following these steps:

  • Make sure that the option "USB Debugging" is activated in the Settings -> Developer options of your device
  • Download the Android app USBMobileMonitor.apk to your device by clicking on the link or going though the Google Playstore and searching for "USB Mobile Monitor"
  • When asked to Preview/Install or Save USBMobileMonitor.apk, click on Preview/Install.
  • When installation is finished, the device will ask you if you want to open the application, do not open the application at this point. The application will open automatically when the device is connected to the PC. The application also closes automatically when the device is disconnected.
  • The first time the application is opened, Android will open a window asking whether you want to always open USB Mobile Monitor when the device is connected, click on "Use By Default for this USB accessory" and tap OK to avoid this window each time you connect the device.

  • Panning the screen using a single touch then moving the finger or pen
  • A left-button mouse click occurs when quickly touching the screen

Troubleshooting Common Issues

Problem 1) My PC has only one display, I would like to configure my device to work as a secondary display, how do I add the second display?

Prior to Windows 10:

Assuming that your graphics card supports multiple displays (most of them do!), follow these steps to add a virtual display to your system, the app will then allow you to switch among the displays:

  • Right-click on the desktop and select "Screen Resolution"
  • Click the "Detect" next to the main monitor
  • Choose "Another display not detected" -> Multiple displays -> Try to connect anyway on VGA
  • This will add a second virtual monitor which you can then configure as a real monitor and view it on your device

Windows 10:
In Windows 10, there is no option to create a virtual display and easily use the USB Mobile Monitor as a second monitor. An alternative is to use a hardware device called loopback adapter, dummy plug or display emulator. There are many models that you can plugin to your HDMI or DisplayPort of your system. These devices usually cost less than 5$ and do a great job. Search for "HDMI Dummy Plug" on Amazon or other online stores and you will find a bunch of these. Once the device is plugged-in, you can see another monitor in Windows 10 and replicate that monitor to your Android device.

Problem 2) After uninstalling the Windows drivers and the application from the device, the device keeps looking for the USB Mobile Monitor application. At the same time, the user cannot go back to the normal device operations such as copying files or using usb debugging.

Solution) This problem occurs when the USB Mobile Monitor Windows drivers have not been removed properly or when Windows cannot find the original drivers for the device. In order to resolve the situation, we created an automated tool that cleans up the Windows PC from any references to USB Mobile Monitor. In order to run this tool:

  • Unplug your device from your PC
  • Download from our website
  • Extract the 3 files that are contained in the package to the temp or any other folder
  • Right-click on the file cleanupusbmm.bat and select "Run as Administrator"
  • Attach the device to the PC and wait a few moments for Windows to recognize the device and reinstall the drivers 

Problem 3) The application on the device shows "Waiting for USB Connection" but nothing else happens

Solution) Various actions can be made to resolve this situation:

  1. NEW: If you are using Windows 10: The latest updates from Microsoft placed additional restrictions on device drivers and require updated drivers for the PC or might even cause system crashes. The device drivers were updated April 2, 2017, it is important that the latest drivers v1.0.1.4 be installed under Windows 10. Follow the instructions outlined below in Problem 4 in order to update the drivers.
  2. Make sure you let the application on the device open automatically. There is no need to launch the application, it should popup automatically when the device is connected to the PC. Unplug the device, wait for the app screen to disappear and plug the device again.
  3. Unplug the device, go to Settings -> Developer Options -> Enable USB Debugging and plug the device back in. Some devices need the USB Debugging option in order to be properly detected by the Windows drivers.
  4. Open the Windows Device Manager. To do so, right-click on Computer -> Properties -> Device Manager. Under Display Adapters, you should see USB Mobile Monitor Mirror Driver. Open Universal Serial Bus Controllers and check that you have a device named USB Mobile Monitor Device. Check if a yellow exclamation mark appears next to one of these 2 devices. If you see a yellow mark, you should reinstall USB Mobile Monitor or contact us at We will need to know the Operating system that you are running and whether it is 32 or 64-bits.

Problem 4) The USB Mobile Monitor devices appear without errors in the Windows 10 Device Manager but nothing happens when the device is connected
