HI, There .

I bought STM32F429I-DISC1 evaluation board.

In first. I download demonstration firmware.

\STM32Cube_FW_F4_V1.21.0\Projects\STM32F429I-Discovery\Demonstrations\STemWin

Run that . feel so good .ST-LINK is active and I can see USB Mass storage.

but not responsed when USB USER connected(CN6).

and freeze when I chooose FileViewer in top nemu.

I think 1more mass storage confirm when USB USER connect.Is it misunderstand?

I checked device manager in windows.it is host of USB.

unknown device was detected.Need I get driver for that device??

Pls help me. How to resolve it or where check ?

Thanks in advance.

Device USB\VID_0483&PID_374B&REV_0100 is the STLink debugger.

The driver for it is available on ST.com.

It has several variants, your variant seems to be a multifunction device and the other function is likely a "virtual COM port".
