sorry if you feel that i am stating the obvious but start from simple things.
did you connect both usb cables to the laptop?
is it possible that you check with a different computer?
can you check device manager to see if the is an "unknown device" or "other devices" (normally windows should notify you about it but sometimes they may glitch)
P.S. i am just another user trying to help, nothing official. i just used these scopes for a couple of years and that's just some advice
