Nucleo f446re USB

I am trying to use USB on the Nucleo F446re and not seeming to have any luck.

I have tried USBSerial usb; for declaration. Even doing this and nothing else locks up my code when loaded to the board. I am not seeing any other examples of USB.

Is there an issue with this Class? or a different way to go about handling USB in mbed?

Thanks

Need more info... You have connected up your own shield with a USB connector and power control on it? I trust you don't mean the debug USB (CN1) on the board. That is a serial connection over to the F446.

I have not put any shield on. I am just at this point wanting to us PA_11/OTG_FS_DM and PA_12/OTG_FS_DP which it shows to be the USB ports in datasheet. right now i have nothing connected to them. I can not even declare USBSerial on those pins without it locking up my code.
