STM32F4 custom board bring-up

I have a custom STM32F411-based board that I am trying to bring-up. But when I plug this into the USB port, I do not see the device listed.
Is there any documentation/guide that can help with initial board bring-up?

I also have a 411-Nucleo that connects just fine over USB, and I can successfully use the mbed environment to build and then flash firmware (using st-link). But I am not sure if a custom board based on the same 411 would need a different way to first get the USB working to flash new firmware using STLink-v2.

Any help would be highly appreciated! Thanks!
