Hello,
I am trying to create a HID device using the USB Device code generation in STM32CubeIDE Version: 1.14.1.
But I have a problem with my PC not recognizing it as a HID device.
MxCube.Version=6.5.0 is working fine and we have investigated the differences within the source code
Undoing the following changes worked correctly.
/**
* @brief Start the USB device
* @PAram hpcd PCD handle
* @retval HAL status
*/
HAL_StatusTypeDef HAL_PCD_Start(PCD_HandleTypeDef *hpcd)
{
USB_OTG_GlobalTypeDef *USBx = hpcd->Instance;
__HAL_LOCK(hpcd);
if (((USBx->CID & (0x1U << 8)) == 0U) &&
(hpcd->Init.battery_charging_enable == 1U))
if ((hpcd->Init.battery_charging_enable == 1U) &&
(hpcd->Init.phy_itface != USB_OTG_ULPI_PHY))
{
/* Enable USB Transceiver */
USBx->GCCFG |= USB_OTG_GCCFG_PWRDWN;
}
__HAL_PCD_ENABLE(hpcd);
(void)USB_DevConnect(hpcd->Instance);
__HAL_UNLOCK(hpcd);
return HAL_OK;
}
/////////////////////////////////////////////////////////////////////////////////////////////
What does this behavior mean?
Best regards
