Resource busy

Hi, I'm trying to downgrade my Unifying dongle with logitech-usb-restore and a VirtualMachine but I'm getting this error:
Could someone help me?
Thank you.
@rafaferreirasantos Did you ever come up with a fix?
No.. I couldn't downgrade. I ended up buying another device.
I figure that the resource needs to be released by the command
usb.util.dispose_resources(self.dongle)
which I've added as the first line in the definition of the function send_command in the unifying.py script.
At least this let me proceed with the flashing of the logitech unifying dongle. Still end up in an error though:
