F411 simply didn't exist when those examples were written. As far as I can tell, you should be using the ogffs_usb_driver, and you'll probably have to do some things to configure your RCC clocks properly, I imagine there may have been some changes, but a cursory check over RM0383 seems to the same as rm0090 for most purposes I can tell.
You should definitely follow Chuck's advice and check that you have the right GPIOs connected, and set to the right modes. You should check that your dev board has a suitable crystal and that you are using it in your clock configuration. You should not have to edit the driver or make a new driver at all.
