STM32Cube 3v1.1.1 USB issue
I use same operator to genertor  example code of USB HID/CDC...etc. on different HW baord.

2. STM32F302CC for My target board
DISCOVERY is okay, my target board is unknown device. On USB handshake, device report Stall.
Then I use STM32_USB-FS-Device_Lib_V4.0.0 to complier and test. It's success.
I suppose my HW is good. I don't why STM32CubeF3 is okay for STM32F303VC, but fail in STM32F302CC.
Please help and give advice, Thany you very much.
