Hi,
You may need a software program to operate the camera as well as the drivers...
Anything you need should be available from the computer manufacturer for your specific model... If you provide that, I will see what I can find if you have no luck...
Try going to Control panel... Right click on Device Manager and select "Run As Administrator" and see if that helps...
The "Show Hardware Changes" should appear\run whether your camera is currently installed or not...
You need to click on the little blue monitor icon below the HELP tab to "Scan For Hardware Changes" on my machine...
You should also be able to click on the "VIEW" tab and "Show Hidden Devices"..
