Sadly, USB streaming was only supported in Windows XP. It is not supported by Vista, Win 7, Win 8, Win8.1 or Win10.
I keep an old Vaio running XP for this and other purposes!
With Win10 you can only use a FireWire/iLink connector and you may need to install a legacy iLink/IEEE 1394 driver - I have not tried it.
The only alternative if FireWire fails to recognise, is to buy an analogue USB video capture device and an analogue AV cable.
