Okay that looks near the same to mine and everyone is correct you need an app for it to work.
The USB cable may also just be for charging, mine is at least. Is this a WIFI unit?
Mine is and to get it to work you need to:
1: connect your phone/computer via wifi to the microscope. Disconnect from your internet wifi and when you turn on the microscope a new network would pop up; this will be the microscope.
2: when connected, the application specified by the manufacturer will now connect to the microscope.
IF IT’S PLUG IN TYPE:
1: you NEED the app recommended by the manufacturer. Then once installed and running it will recognize your USB microscope when on and connected to the computer.
Do you have the box for it @olschool ? Or where did you order it from at least?
