Hello.

NUCLEO F411RE, Workbench generated project, Ubuntu 64 16.04, STCUbeMX , I think is  V1.18

I wired a USB cable to USB-DP (PA12)  USB-DM (PA11) GND and 5V.

I have a usb initialised as simple as instructed.

void MX_USB_DEVICE_Init(void)

    {    USBD_Init(&hUsbDeviceFS, &FS_Desc, DEVICE_FS);    USBD_RegisterClass(&hUsbDeviceFS, &USBD_CDC);

    USBD_CDC_RegisterInterface(&hUsbDeviceFS, &USBD_Interface_fops_FS);

    USBD_Start(&hUsbDeviceFS);

    }

When I plug in the USB I cannot see the device. I could not find a solution.

Hello

,

Check if your VCP driver is correctly installed on PC, and try to increase heap and stack sizes.

May be this is due to VBUS sensing it must be set do Disable.

Note: Please use the last version of STM32CubeMx (v4.23)

Kind Regards,

Hi, Thank you. I figure it out meanwhile with help from a HW engineer.

The Nucleos F411re I have has the 8Mhz crystal on the Sllink side. On Nucleo side,

• I removed the SB16MCO 0 ohm resistor on the back close to crystal holes.
• I soldered a 25 Mhz crystal and the 2 caps C33 and C44  ~15pf where crystal was missing,
• I changed the clock in hal*.h from 8Mhz to 25Mhz

 sudo dmesg -c
