boot camp when in windows my usb port is not working at all

I just finished doing boot camp and can log into Windows but my USB port is not working at all. The main reason I am using windows is because of photoshop and games and such and so I need my USB port so I can use my mouse and my wacom tablet but they are not connecting. Also, my usb memory stick won't even work when I switch over either. Is there anyone that can help me?
