STM32G0B1 USB device not recognized in Windows 10

Hello,

I'm using STM32G0B1-Nucleo (with no USB user connector), and I am trying to program USB device (I tried virtual COM, HID and MSC separately).

I'm using the STM32CubeMx with STM32CubeG0 FW V1.5.1 to generate the configuration with PA12 and PA11 for D+ and D-.

But after plugging into PC it is detected (after a while) with "Unknown device (device descriptor request failed)" error. (see img bellow)

Notes:

1- I have used the same USB Wire to connect the board with the PC on STM32L476-Nucelo (with no USB user connector also) and STM32F4 Disco and it works fine for both, so I don't think it is related to the wire or the configuration I'm using.

2- The STM32G0B1 Nucleo I'm using is a new one, I just purchased it for this application.

3- I have tried to use the STM32G0C1-EV application provided in the Cube FW but with no success.

Please find attached the .ioc file and the main.c of my project.

Any Idea about this issue and how to fix it please?

Thanks.

Hi @jpichingo

if you are using CubeMx, I think that it is a bug in the tools that should automatically activate the usb interrupt.

in fact, the USB is based on the interrupt routine and cannot works if the interrupt is not activated. even for other devices when activating the USB, the interrupt is activated automatically and cannot even be deactivated which is not the case if you are using the stm32g0, you need to activate it manually in the interrupt interface. ( @Amel NASRI maybe it should be fixed in the CubeMx tool)

if you are not using the Mx tools, make sure that you have activated the usb interrupt.

Hello @Houssem ,

You can refer to the following example provided under the G0 Firmware Package:

Path: Projects\NUCLEO-G0B1RE\Applications\USB_Device\CDC_Standalone

Please let me know if this example works well from your side and if you still have the problem of the unrecognized USB device.

BeST Regards,

Hi @Walid ZRELLI

There is no USB Application provided for NUCLEO-G0B1RE.

That would be great if there is one.

Please note that I have tried with both STM32CubeG0_FW v1.5.1 (USB_Device v2.8.0) and STM32CubeG0_FW v1.4.1 (USB_Device v2.7.1)

Hello @Houssem ,

Sorry for the confusion. The example mentioned in the comment above no longer exists.

You can refer to other examples developed on other boards and port them to your board.

BeST Regards,

Hi @Walid ZRELLI

Thanks for reply.

Unfortunately, I have already tried your recommendations with no success:

Notes:

1- I have used the same USB Wire to connect the board with the PC on STM32L476-Nucelo (with no USB user connector also) and STM32F4 Disco and it works fine for both, so I don't think it is related to the wire or the configuration I'm using.

2- The STM32G0B1 Nucleo I'm using is a new one, I just purchased it for this application.

3- I have tried to use the STM32G0C1-EV application provided in the Cube FW but with no success.

Besides, you can find my ioc project and main.c attached.

Any other suggestion please?

Thanks.
