Welcome to the Plugable forums! I can certainly assist you with setup for our USB 2.0 Digital Microscope! To get started with using our microscope I would suggest to download our “Digital Viewer” application which will detect the microscope and function as a viewfinder.
Another way to use the microscope is to open up the “Camera” application within Windows, this is an application that is built into the operating system so you should have this preinstalled.
Once either of these applications are opened the light on the Digital Microscope should turn on, you may need to adjust the grey light dial to the right in order to increase brightness.
If you happen to have another webcam on your computer we may need to change which camera is selected within the application. In Digital Viewer select the “Gear” Icon > Device Setup > Device.
I will also leave a link to where our application “Digital Viewer” can be downloaded.
It is normal behavior that when plugged in for the device to not show up in any folders although it will show up as “Digital Microscope” in Device Manager.
I hope this information helps and let us know if you need any further assistance setting up the microscope!
