hi,
i am Using STM32G0B1RCT6
USB_CLK = 48MHZ
USB_DRD_FS---Host_Only_FS,
USB_HOST---Mass Storage Host Class,
FATFS---USB Disk
USB Interrupt---Enable
If you set it to the above mode and operate it, the USB is recognized and i configured PB4 as an output, which is connected to a green LED. Whenever I plug in the USB to my controller, the green light appears, and whenever I remove the USB from the controller, the green light turns off. so usb detected successfully, but the USB Mount/Unmount function does not work.
It works fine with stm32f429zit6 with same configuration. What causes it? how to solve this problem?
static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id)
{
/* USER CODE BEGIN CALL_BACK_1 */
switch(id)
{
case HOST_USER_SELECT_CONFIGURATION:
break;
case HOST_USER_DISCONNECTION:
Appli_state = APPLICATION_DISCONNECT;
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_4, RESET);
Unmount_USB();
break;
case HOST_USER_CLASS_ACTIVE:
Appli_state = APPLICATION_READY;
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_4, SET);
Mount_USB();
Check_USB_Details();//check Space Details
Scan_USB("/");//Scan for files and Directories
Create_File("/ROOTFILE.csv");
char csv_data[] = "Name, Age, Salary\n\nBerlin, 27, 60000\nAlice, 28, 55000\nAlbert, 32, 55000\n";
Write_CSV_File("ROOTFILE.csv", csv_data);
break;
case HOST_USER_CONNECTION:
Appli_state = APPLICATION_START;
break;
default:
break;
}

It seems you have custom implementation of Mount_USB() Unmount_USB() and they are not defined. Would you mind clarify?
Did you try the example using FatFs
