Hello ST,

Here i am using STM32F723E-DISCO demo board developing the USB Slave Mass Storage application, using the CubeMX generating the code for a test, the procedure is below.

  1. select STM32F723IEK MCU;
  2. select System Core -> RCC -> HSE: BYPASS Clock Source;

8. download to board and connect USB HS cable;

the windows shows a mass storage device in device management list, but it shows errors like below.
