it is a red suare usb with a blue circle in the middle. Then there is adapters that u can take off with audio cables, video cables and another port that i cannot use.
Okay, so yours has the Red/White/Yellow ports plus I think probably a 4 pin S-Video which is a special adaptor (not used often, and not necessary)
If you are not getting video to transmit correctly, make sure the program and any updates for the program are installed, plus if there is any extra driver information for the device, make sure it is installed.
