Hi, I receive the following errors when I attempt to use native USB redirection in RHEV 3.1 beta. It's a smart card reader I am attempting to redirect into a virtual Windows 7 x64 machine. Is this a known error? I've also posted this message to the spice-devel list. Not sure which list is the correct list for this issue.
