STM32F303 USB VCP device not showing up - windows 10

[GPavl]

I'm having issues getting USB to work on STM32F303RE. The device doesn't show on windows machine. I'm using 24 MHz 10ppm external xtal. I generated initialisation code for keil with cubemx (using STM32Cube FW_F3 V1.10.0) with just USB enabled and it doesn't work. I double checked every connection in pinouts. You can find clock configuration attached. Is there a bug in USB drivers? I tried using older FW with no success.

Is it recognized as an Unknown Device or it does not show at all ?

It doesn't show at all. Program also runs to main loop without errors in initialisation.
