Some specific device classes, such as USB cameras, are handled differently by operating system privacy/security settings. If you aren't seeing an image output from the microscope, or you see a message that your "Camera is being used by another application", you may need to change these privacy/security settings.

Instructions for Windows

1. Press the or click on the Windows key to open the Start Menu, and type "Settings" into the search bar.
   
   
2. Then, click the gear-shaped icon to open up the Settings menu.

You must manually launch Digital Viewer or another webcam suite in order to use the microscope, nothing happens automatically when the microscope is attached to a USB port. The microscope’s LEDs won’t turn on unless the device is being accessed by an application.

First, make sure that the microscope is set as the default device in the Settings menu. The Settings menu can be opened by clicking on the grey gear-shaped icon in the upper left corner of the Digital Viewer window.

In some cases, the devices in this menu have the wrong name. If you have the microscope selected in this menu and still see output from another webcam, try selecting each device in this menu until the preview window shows output from the microscope.

Windows Camera Mix-up Issues

Windows has a specific issue that can pop up with the microscope. The microscope uses the same USB Video Class drivers as most built-in and external cameras which can cause Windows to mix-up the listing.

If you set the microscope as the default device but see your other camera its likely that the listing was mixed up. To check if listing was mixed up, try picking your other camera from the drop down menu, and see if the microscope view shows up instead.

If the microscope view shows up on your monitor after picking your other camera, the listing was mixed up. There are steps that we could try to see if we can fix the listing. We do need to be clear, that as this is a Windows issue, it may reoccur with Windows Updates and other events. Let's give these steps a try to see if it clears the listing up:

1. Press the Windows Key, and type in Device Manager. You should see a listing for the Device Manager in the search. Click on it to open the Device Manager
   
   
   
   
2. Now that we have the Device Manager open, click on View, and choose Show Hidden Devices. We want to be sure to remove all entries related to the microscope
   
   
   
   
3. The microscope should show up in the Cameras section, but it may show up in Imaging Devices. Click the little arrow on these sections to expand the listings, and find the "USB Microscope" Listing (In the picture below, mine is right next to the on-board camera Windows is confusing it with.) You may see other listings that appear faint, or grayed out, which is why we checked for Hidden Devices
   
   
   

Once you've found the listing(s), try these steps:

1. Right Click on the USB Microscope, and click to Uninstall Device for each listing you see
   
   
   
   
2. A message will pop-up telling you that you're about to uninstall the device from your computer. Click Uninstall to proceed
   
   
   
   
3. Restart the computer after the microscope has been uninstalled. After you restart, open the Digital Viewer software only, and check to see if the microscope shows up when you set it as the Default Device.

Regrettably, iOS does not support external USB cameras, so no device that runs iOS will work with any USB camera.

Locating Digital Viewer

Android support is on a case by case basis. The manufacturer of the Android device must allow USB webcams or this will not work.

The microscope uses the same chipset as the Oculus DK2 sensors making the system believe it is just an additional Oculus sensor. In order to help the operating system correctly identify the microscope as a USB camera, we must change which driver the microscope uses. The steps below should correct this problem.

1. Disconnect all Oculus Rift devices.
2. Connect the microscope.
3. Open the Device Manager in Windows. This can be done several ways, if you’re uncertain how to access Device Manager perform these steps:
   • Press the Windows key and R (Win + R).
   • In the window that pops up, type devmgmt.msc, then click OK
4. Look for the microscope. It will likely be listed as a Rift DK2 sensor, under Oculus VR Devices.
   • If you’re not certain if you found it, disconnect the microscope and the entry should disappear. Reconnect the microscope and the entry should come back, that’s how we’ll know for certain we’re looking at the correct device.
5. Once you've identified the microscope, right-click on it and choose Update Driver > Browse My Computer For Driver Software > Let Me Pick From A List Of Device Drivers On My Computer
6. Select USB Video Device, then click Next to complete the driver installation.

NOTE: After completing these steps, Windows will still name the microscope as "Rift DK2 Sensor". To confirm these steps worked, look for an entry for Rift DK2 Sensor under Imaging Devices. You must select "Rift DK2 Sensor" to use the microscope in Plugable Digital Viewer or other applications.

From the factory, the LED control is in the off position. For most indoor lighting conditions, you will need to turn the LEDs on by rotating the grey light control wheel in order to see anything.

In some cases, this happens because the software does not have permission to access the microscope. If so, security settings in your operating system must be modified.

In a recent review of the Digital Viewer software, a typo was discovered in the maximum file size limitation instructions under Movie Setup. When the maximum file size is entered as shown (4097 MB), the following error message is displayed: “Video size setting is incorrect; out of range.” As a workaround, customers should enter 4096MB (or lower) as the maximum file size.

Make sure to click ‘Apply’ after your changes have been made.

Note: The Maximum File Size is a limitation of the software currently and may be raised at a later date in an updated version. We will update this document accordingly at that time

With microscopes on Chromebook, we need to be sure to check a few things:

1. We need to make sure that the Chromebook operating system is up to date. To do so, go into  Settings > About Chrome OS > Check for updates. If an update is available, please let it run. (Click here, for official information from Google about updating.)
   
   
2. After that, let's check and make sure that the Camera app is the current version from the Chrome Webstore: Chromebook Camera App
   
   
3. Restart the Chromebook after the updates to make sure they finalize
   
   
4. After reboot, connect the microscope and launch the Camera App
   
   
5. In the bottom left hand corner, there is a button with two arrows rotating around a circle. This button is there to "Switch to next camera". Click the button to switch over to the microscope

It sounds like the Time Lapse mode is on. This mode will continually take pictures at preset intervals until you click the button again to Stop Time Lapse.

Let's check and see if Time Lapse mode is on:

1. Open the Digital Viewer software
   
   
2. Hover your mouse over the icon of a camera with a clock inside, and see if a message pops up that says Stop Time Lapse
   
   
   
3. Click the button and the Time Lapse mode should stop

Yes. Our Plugable USB2-MICRO-250X Digital USB Microscope must be used with software to process, display, and capture images and video.

Where can I get the software?

We offer our free Digital Viewer software package for use with the microscope on Windows and macOS! You can also use other camera software packages such as:

• Windows Camera on Windows 
  
  
• Photo Booth on macOS
  
  
• Webcamoid on Windows , macOS, and Linux
  
  
• Cheese on Linux , and very useful on Raspberry Pi systems
  
  
• Google Camera on Chromebooks . Chromebooks use the built in Camera application, and need to be updated regularly for overall functionality. You may want to check with your Chromebook manufacturer for more information about your model

Great! I've downloaded and installed some software. What do I do now?

We need to start the software, and set the microscope as the default device. Using our Digital Viewer software as an example, here's some basic steps to get you started:

1. Restart the computer for changes from installation to take full effect
2. Plug the microscope in to a USB port
3. Start the software, and go into the Settings menu by clicking the Gear-shaped icon in the top left corner of the Digital Viewer screen
   
   
   
4. Then, click on the drop-down menu and set the microscope as the default device. Click Apply when you're finished
   
   

You should now be able to see the microscope image appear, and be ready to examine things! This is a fairly typical setup for most camera programs. But, it's always a good idea to review any instructions from the application developer for specifics.

We see a lot of people use the microscope for their coin and stamp collections, plants, circuits, and other hobbies. Here's an example of a few items under the microscope, including a speckled vinyl record, some moss spores, and a quarter:
