Hi, i'm using STM32f407 for a USB project. I use CDC class (STM32_USB_Device_Library) for implementing USB device on my OLIMEX EVAL board.
When i connect my board to PC, it appear as VCP, but device manager says: "This device cannot start. (Code 10)".

In the forum I found that the solution is to change the values of HEAP and STACK in startup file, but in my startup file i don't have HEAP and STACK size (file attached). Why?
What instructions i have to add in the startup code?

thank you all!
