White external device connection adapter, compatible with composite/S-Video/VGA. - Connection terminals: Composite, S-Video, VGA, USB port - Color: White - Fan: Equipped with two cooling fans - Function: External device connection adapter Thank you for viewing. This is the DIGITAL COWBOY GA-CX1005XB. I believe the function is to cool with the rear FAN while also supporting various outputs. I have cleaned it roughly, but not the inside of the fan or the terminals. It is generally yellowed. Also, it seems to only work with relatively early model 360s. Currently, operation is unconfirmed, so it is treated as junk. I will pack and send it as is. I do not have a main unit to test its operation, so I cannot confirm its functionality. Please only purchase if you understand this.
