I made a small project for USB device with STM32F415, but I have a problem. I receive setup data from the PC on EP0 , but when I write data (which should come out from Device to Host) these data not exit.

Moving a line of your code, on EP0StartXfer, everything works.

Can be a concept bug on your code ?

  * @file    stm32f4xx_ll_usb.c
  * @version V1.5.1
  * @date    01-July-2016
  * @brief   USB Low Layer HAL module driver.

Enclosed is a video of problem with the USB analyzer.

Sorry for my poor english
