Comment 4 for bug 1791947

I have already posted a reply on Qemu-devel since everything posted here is automatically forwarded to Qemu-devel, however, the opposite is not true. So duplicating my reply on Qemu-devel:

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?

Thanks!
