How exactly do you use USB redirection: via virt-manager or via spice client (like remote viewer)? If via spice-client, on which OS the client runs? In this case running it with --spice-debug and collecting logs from stdio and stderr could be helpful. Can you also provide a usbpcap capture of the usb device's traffic from within the VM?
