This message is shown by Spice's USB redirection code when USB device
is used, and the device gets rejected by the policy. In this case the xml
which you quote will only allow one specific device to be redirected.
If you remove the entire <redirfilter> ... </redirfilter> block from
config for your vm, then the message should go away, and you should be
redirect any device.
Hans, thank you very much. Removing the filter un-greyed the USB
devices. Obviously, I don't understand the filtering element - yet :).
I was hoping I'd be able to report that Rocksmith 2014 works great.
Unfortunately, although it installed without a problem, I am now
tracking down why it is generating a "Unable to initialize graphics
system" dialog <sigh>. So much for being an uber-geek. BTW, have any
of you played with the nwfilter feature of KVM? I ran into an odd bug
a while back and
there hasn't been any movement on it. I came up with a rubber band and
bubblegum solution which I mention in the bug report, so it's not an
emergency, just annoying. Spice is way cool as is this USB redirection
feature. Thank you both for writing it and help me.
