USB Com not available

[geocheats2]

Hello to everyone

I have a custom PCB with STMf407IGT and i have ported Arduino_Core_STM32 and works just fine when flashed using ST-LINK
and the serial com works, i compiled STM32_HID_Bootloader for my MCU (diff clock) and while it flashes just fine using the following settings on Arduino IDE i don't seem to be able to make the USB Com Port available on my device manager.

Do you have any ideas at what to look??

I think you don't have to select a COM port.
And arduino ide 1.85+ don't work with hid-bootloader. But you have a lower version.

1.85? What is that? Arduino versions are three digits, like maybe 1.8.5 but that's too old, the newest 1.8.x I could find is 1.8.19 from 2021. Version 2 became available around that time.
