My microscope is still showing my web cam even after I select usb camera in the settings what am I doing wrong? I have tried rebooting and reinstalling. I am on a Lenovo running windows 10

Are you saying that you only see your webcam through the software, or that you have to change it in order for the microscope to work?

The software will always use the default video device first upon launch. In this case, since you have a built in webcam, that would be the default.
