USBx MSC demo not working on stm32h5 discovery board

[Sidewinder]

I've just brought the stm32h573i-dk dev board and what to become familiar with Threadx and USBx. I have a uni project coming up that I would like to use the board as a msc device but struggling to get the board to enumerate with the PC. I have tried to get majority of the USBx reference designs up and running. They compile fine but nothing happens when I connect the board to a PC on cn17 ( the non stl-link usb). Is there anything I'm doing  wrong to get it up and running . Is there something I need to enable to for the USB port to work? 

I also have a couple of u5 and h5 nucleo boards I would also like to get up and running With various forms of USB Once I have the discovery board working. Any pointers would be greatly welcome. Thanks

Hi @Sidewinder 

Did you insert SD card before application is started?

Would you specify boards revision. Is it MB1677-C01?

Hi FBL,

I have just revisited looking at the USBx examples but used a different USBc cable and  all examples

work. It looks like a power only cable had got mixed in with the cables.
