Re: [Qemu-devel] [Bug 1791947] Re: isochronous usb device forwarding with windows 10 and xhci freezes

[Sameeh Jubran]

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?
