Hi all,

i want to build my own STM32 PCB with USB connection, I want to use the USB communication for sending Data via VCP(CDC) to the PC and to programm the STM32 via DFU. Currently I'm using the discovery board and everthing works fine. My question is, do i need the Current limiter for that? I looked in the Datasheet at page 185, but i'm still not 100% sure. Maybe someone can help me. Thanks in advance :)

    You only need the current limiter when using the device in host mode.
