Here's the link to the project: https://github.com/qwer-zxcv/stm32f429_usb_cdc_tinyusb Please help me out!

What happened ?

Initializing full speed usb cdc device has not been enumerated, no response from usb

How to reproduce ?

I had the same problem and fixed it by commenting out autogenerated MX_USB_OTG_FS_PCD_Init and replace it with the following code.

  GPIO_InitTypeDef GPIO_InitStruct;

  /* Configure USB FS GPIOs */
  __HAL_RCC_GPIOA_CLK_ENABLE();

  /* Configure USB D+ D- Pins */
  GPIO_InitStruct.Pin = GPIO_PIN_11 | GPIO_PIN_12;
  GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
  GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Alternate = GPIO_AF10_OTG_FS;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  /* Configure VBUS Pin */
  GPIO_InitStruct.Pin = GPIO_PIN_9;
  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  /* ID Pin */
  GPIO_InitStruct.Pin = GPIO_PIN_10;
  GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
  GPIO_InitStruct.Pull = GPIO_PULLUP;
  GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
  GPIO_InitStruct.Alternate = GPIO_AF10_OTG_FS;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  // Enable USB OTG clock
  __HAL_RCC_USB_OTG_FS_CLK_ENABLE();

  // STM32F401 doesn't use VBUS sense (B device); explicitly disable it
  USB_OTG_FS->GCCFG |= USB_OTG_GCCFG_NOVBUSSENS;
  USB_OTG_FS->GCCFG &= ~USB_OTG_GCCFG_VBUSBSEN;
  USB_OTG_FS->GCCFG &= ~USB_OTG_GCCFG_VBUSASEN;
