STM32CubeProgrammer not working with STM32F072 for USB DFU

I have a design that I'm trying to bring up and program using the USB DFU capability. The board enumerates correctly in windows, but does not get into programming. It seems as though I have forgotten something, but don't know what to look for. I have checked the "Read Unprotect (MCU)" box.

I have attached the verbose log of one cycle. What happens when I try to connect is shown there and after a bit a window pops up saying to turn off the power to my device. When I do, the cycle repeats!

Thanks for any pointers...

Is there any update to this problem from the ST devs? How close are we to this being solved?

(I also was able to solve this behaviour through a USB Hub)

Best,
