Hi All,

Iam trying to configure STM32F4 discovery board to detect as mouse in Windows PC.

I have generated code from STM32CubeMX tool and configurations are HSE_VALUE = 25MHZ, usb device class is HID. When Am running code PC is detecting STM board as unknown device i.e., it is not getting enumerate. Later I got to know that the device is stucked at Default Adress and stm is not getting device descriptor request from HUB.

Please, help me out from this problem.

Thanks in advance...

The board uses an 8 MHz clock source, HSE_VALUE needs to reflect that.

Hi Clive One,

Thanks for your reply. It is working after change of HSE_VALUE to 8 MHZ from 25 MHZ.
