Please note: 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 to see anything.
 

When you connect a Plugable USB2-MICRO-250X microscope to your system, the LED light will NOT turn on automatically.  You must manually launch Digital Viewer or another webcam software to use the microscope.  The LED will power on when the device is in use 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, such as iPhone, 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.

It is very exciting to see that iPads are now compatible with external cameras like our USB2-MICRO-250X! In order to use our microscope iPads must have:

• A USB C port
• iPadOS version 17.x or higher

You'll also need to install an additional camera app to see the microscope image like:

• CamX
• USB Camera

We've tested and confirmed compatibility with the apps listed above, but there are surely other compatible apps as well. After installing an app, start it with the microscope plugged in and you should see the microscope image. You may have to go into the settings for the camera app, and set the microscope as the default app.

We hope this was helpful! Have you found a compatible app you'd like to share? Feel free to reach out to us directly at: support@plugable.com with any questions or concerns!

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

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:

In this knowledge base article, we aim to clarify the functionality of our USB2-MICRO-250X microscope, particularly regarding magnification and focus capabilities.

Understanding Magnification and Focus:

The USB2-MICRO-250X microscope does not feature a traditional zoom function. Instead, it offers magnification and focus functionalities to achieve varying levels of "zoom." Users can adjust the magnification and focus by moving the microscope closer to the object and adjusting the focus accordingly.

However, it's essential to note that our microscope does not have a digital zoom like some other cameras. Instead, it utilizes digital focus adjustment and magnification.

Usage Instructions:

1. Begin by placing the microscope on the observation pad grid, nose-down, and resting on the clear shield.
2. Rotate the focus lens mechanism fully in one direction until it stops.
3. Slowly rotate the focus lens mechanism in the opposite direction while observing the changes in the preview window of the Digital Viewer app until the object is in focus.

Observations:

• At the closest distance with the clear shield touching the object, there are two possible magnifications.
• The first magnification is approximately 60x, but by continuing to rotate the focus wheel, the image will initially become blurry and then sharp again at a much higher magnification.
• There are two focal points with the clear shield touching the object, offering focus at two magnification levels.
