Hi,

Thanks @KDJEM.1 .

But i solved my problem. When i bought my MCU, the reference which write on the chipset was not the same on the product description on the website.

I configure my project to the correct reference STM32F103C8XX to STM32F103C6XX and now all working fine!

Hi @FBOCA.1 ,

Try to increase the heap size, or configure the USB library to use static allocation.

For more explanation, I advise you to follow this article to solve the problem.

Make sure also that you are not facing this particular case.
