Hi, you need a bit more than just virt-viewer to make USB redirection on Windows working. It was already summarized on this list in the past: http://lists.freedesktop.org/archives/spice-devel/2013-April/013214.html http://lists.freedesktop.org/archives/spice-devel/2013-May/013479.html HTH, David On Čt, 2014-03-27 at 10:12 +0800, 付乐颖 wrote: > Hello. I have installed the spice server， and after the spice-gtk configure, it shows the usb redirection is yes. But when i installed the virt-viewer 64-bit in my windows8, the virt-viewer still can not support the usb redirect, the option of "USB device selection" is gray. But virt-viewer in my Ubuntu can support the USB redirection. Should I install some other dependencies in my Windows? And what's that? Could you tell me?
