HP50G USB drivers - Win10 64bit errors

[Stevetuc]

I managed to load the win7 64 bit drivers from here:
https://support.hp.com/gb-en/drivers/sel...or/3235173
by turning off driver enforcing in Win10

However, when I attach HP50G, I get "USB device not recognised"

In Device Manager, I see Unknown USB Device(Device Descriptor Request Failed)
and clicking on that the device status shows that Windows has stopped the device because its reported problems (code 43)

Due to above, clicking on Driver Details says that no driver files are loaded or required for this device.

In case its relevant, I'm running Win10 64bit under Bootcamp

Any ideas how I can fix this?
