Hi

''i use stm32f4 discovery board .''

Is the board you are talking about this one :

'' i want to use usb''

'' i just want transfer data between pc and stm32f4''

HID = Human interface device (eg mouse, keyboard or joystick)

CDC = serial comms device (eg virtual RS232)

MSC = Mass Storage Device (eg memory stick)

CDC is probably the easiest.

On the link above - look under ''Related Tools and Software''

''

STM32F4DISCOVERY board firmware package, including 22 examples (covering USB Host, audio, MEMS accelerometer and microphone) (AN3983)

''

Should have some examples for USB devices

Here is the library code for USB :

It should contain examples of USB devices (including USB CDC - serial device).

The examples are for the range of processors (not specific for your board).

(I think the CDC example also mixes USB CDC with the USART)
