ST-LINK on STM32L552E-EVAL board

[DYann.1]

Hello,

I have a evaluation board STM32L552E-EVAL, and I would like to know what is this part used for ?

I see 2 pins (USB_D_N and USB_D_P) that connect to the STM32F103CBT6

What is it for ? To program the component and debug. Thank you for your answer

Regards
