stm32f105 Device Only issues

HI

I am struggling to set up USB Device only on stm32f105

I do set up following

  1. RCC - Crystal resonator
  2. SYS - Debug Serial wire
  3. USB_OTG - Device only
  4. USB Device - CDC
  5. Clock I set up 8MHz and run resolve
  6. Build project and load firmware

And after connecting to PC nothing happens at all.

I have the same issue with f730 for some reason, but it works on f103 (different setup) and f407. I really don't get it what I am doing wrong.
