It's the Boot Camp drivers. You must install them into Windows to make the computer work correctly. To download them, press X key while your computer is starting to start into OS X, open Boot Camp Assistant and download the Windows support software. Then, start into Windows and install the Boot Camp drivers
Thank you mende1, I already installed the drivers when I installed windows.
Now i downloaded the drivers again from the boot camp assistant and re-installed, but after the reboot nothing changed.
I read that many peolple had my same problem, and found no solution.
It's very frustrating and a waste of time switching to mac os x every time I need to download a picture from my camera.
