USB Package do not work

Hello,

I have an Olimex board with an STM32F107 cpu on it.
It start in the bootloader and I can upload firmware to it.
For this I use CubeIDE and CubeProgrammer.

I need to give USB support to my application so that to communicate with a PC.

In CubeIDE, I have initialized USB_OTG_FS (without SOF signal as my cpu does not support it)

I then regenarated code and recompile (through right click on project name then "Build project").
Then program the cpu.
Then Reset the cpu but it does not work (I do not hear beep as when a new USB device is connected) ?

Do you have an idea on what happens ?

Thanks in advance for your help.
Kind regards,
