To confirm that you have a USB 2.0 header, you’ll see that the label on the motherboard mentions ‘USB 2.0’. Well, this is one of the most common headers and is located in the bottom part of most motherboards. Available in four different types, the USB headers correspond to the generation and version of the Universal Serial Bus.

While the USB 3.0, 3.1, and 3.2 headers are single-channeled, the USB 3.2 Gen 2×2 supports dual channels. If the wires aren’t properly connected, the PC won’t recognize your USB devices, and in the worst case, this may cause short-circuiting. So, please follow the below procedure to get an idea of how to properly connect the individual USB port wires to the USB headers:

Apple cancelled this, now what?

A header actually refers to the shortened form of pin header, but a connector is what you plug into the header

Now that you know the different types of USB headers, it’s essential to learn about the internal USB cable. Basically, they are the extension cables that let you attach the USB ports to the USB headers.

Although they look pretty similar to the USB 2.0 headers, they are comparatively more efficient. Moreover, they have a total of nineteen pins in a 10×2 arrangement, ten pins in the first row and nine in the second. As in the USB 2.0 headers, they also have a pin missing in the second row.

If it is a 2X5-pin header, there will be two S-GND pins and one connector should be left unconnected. You can even use a USB hub to access a more significant number of USB devices. Basically, the device takes just one USB port from your PC and provides you with several additional USB ports. There are four basic types of USB headers such as USB 2.0 header, USB 3.0 header, USB 3.0 3.1 Gen 2 header, and 3.2 Gen 2 x 2 header. The driver polls the device periodically to see if there is anything to communicate and performs the transactions until the device is removed.
