HS USB device with no external Phy on stm32f2xx

Folks

reviewing my code and the recent changes to the RL libs etc

I use the HS USB as a device in the bootloader code and the FS as a host in the application

At the time I wrote the code there was no Keil driver for the HS port if did not use an external Phy

I have had a attempt at now removing the ST code and just using the Keil RL libs and so far its failed to work as expected ( the PC does not recognise the USB device attached)
Plus once its started and I want to return to the bootloader I get endless hard faults ( which I have not seen before )

So I am assuming someone out there has a working version

When you config the USB what settings do you use

e.g.

#define __OTG_HS_EMBEDDED_PHY

HS or not
size of the data package 512 or 64

Looking at the examples and boards I am not aware of one that does not use the external UPLI phy

So can anyone help out and point me in the right direction ?
