Hi, I'm making CDC device function on the STM32Cube and STM32F4Discovery.
But the USB communication between above and PC(Windows 7 32bit) is interrupted as "STALL" after GET_DESCRIPTER(DEVICE QUALIFIER) message and SET_CONFIGURATION message absolutely.

How can I avoid above errors?

Could you please give me any idea?
