Video capture by microscope camera

1. How to use C-sharp or CPP to get the video image of microscope camera?
2. You can only get the camera image of the notebook through AForge, so why can"t you find the microscope camera device?
3. Can you get the video image of the microscope camera only through the SDK or API provided by the equipment manufacturer?
Note:
microscope camera model: OLYMPUS LC30 USB interface
