Another wasted hour, found the 'blackmagic.bin' files BUT there are several, which one works?
Told to get Zadig to 'fix' my windows, finally got 618 and 617 PID
but then had to hunt for a windows version of dfu-util
finally:
D:\Downloads\BlackMagic\win64>dfu-util.exe -d 1d50:6018,:6017 -s 0x08002000:leave -D blackmagic-native.bin
dfu-util 0.11
