Core 2 internal 4pin connector

[fargoblueberry]

Hi @all!
I am completely new to the world of developing anything that controls kind of hardware, so please be patient. I used to program backend-services for IoT devices, but never touched the devices in any way :)

I got the Core2 and now I am searching for a drawing like this:

Is there any picture like this for the Core 2 - I wasn't able to find one and hope I am not just too stupid to use search engines.

Espacially I want to know what this 4 pin connector in the inside is.
It's marked with DM | DP | GND | 5V
When I google this I end up with USB. Is this kind of an internal USB-Connector?
What can I use it for?

Thank you guys!

So basically, the question is: what’s that connector for?
