See included photo for what USB should look like
"Apparently this cable is for the v1 VTX but there's nothing in the product description to let buyers know that it only works with the v1 VTX. There is a different connector for practically every version of the VTX and the manufacturer has done a poor job of communicating this to retailers. They also include the wrong cable with some of their VTX units. See the included photo to see what a USB port should look like."
