Hello @ABhat.7​ ,

Which Cube package version are you using ? Make sure that you are using the version V1.8.1 (that contains USB update) or upper.

Have you made any changes on the provided example?

Check the heap and stack sizes defined in the startup.s (should be increased).

Please mark my answer as best by clicking on the "Select as Best" button if it helped.

If you still need help, feel free to ask your question in more detail.

Use an effective Hard Fault Handler and debug the situation..

Stack or Heap size issues?

In any case you're going to have to get a lot more into the details to understand why it is not working.

Hi @ABhat.7​ ,

Sorry for the delay to answer you, as I'm working from home and I haven't the STM32F107 board at home.

But, after checking your ioc file, there are some warnings to configure USB parameters in the Platform Settings Tab.

When running your project, I get several errors and warnings.

I recommend you to use the CubeF1 version V1.8.1 or upper (as contains USB update and enhancements) and refer to the USB MSC example with STM32CubeF1 MCU package:

STM32Cube_FW_F1_V1.x.x\Projects\STM3210C_EVAL\Applications\USB_Host\MSC_Standalone

You can use the example code provided and compare the code/functions with yours.
