Failure to verify the driver will result in the following:
1) Can't find the microscope device.

2) The "GL USB2.0 UVC Camera Device" in "Device Manager" appears a yellow triangle.

Windows cannot verify the digital signature "GL USB2.0 UVC Camera Device" (this driver can make the zoom button work on Amcap). To solve this problem, we can
(1)Disable Secure Boot in BIOS settings to get the driver verified by Windows.
(2)Uninstall the "GL USB2.0 UVC Camera Device". The computer will automatically install a generic driver instead.
