STM32F205RGY6 and USB FS problem

I am trying to make USB works on Sony SmartWatch with STM32F205RG. I don't have scheme but I am 90% sure that watch uses PA11/12 for USB FS.

I addopted ST's USB FS library and currently I have this :
- watch is detected as USB device
- windows detection failed during enumeration

I think that timing is ok (HSE is 26Mhz but I think that USB running well on 48Mhz) because when I touch it, it ends to device which is unable to connect to PC.

It looks that I am getting only some of interrupts because Setup operation is never called (I am printing debug info on 128x128 OLED).

Have somebody idea what to check and verify ?

I have JTag debugger but I don't like to open watches just to see if there is chance to connect JTag
