it is a privilege for me that the manteiner takes this post of mine into consideration, I am happy about it. after installing windows (I tried both win7 and 10) I immediately installed this sw: -space.org/download/windows/spice-guest-tools/spice-guest-tools-latest.exe but, as I wrote in the first post, if I attack a USB device (usb, usb3) windows (7 e 10) tries to configure it but can not and therefore can not be used.
