Additional info:

Worked fine in Fedora 20.

Comment 1 Ján Tomko 2014-09-24 12:41:50 UTC
I don't see any usb-host device on the command line. Is there a <hostdev> in the domain XML?

Yep, it is there.

My guess was that libvirt attaches the device via usb_add in the qemu console prior to starting the guest cpu?

Comment 3 Cole Robinson 2014-09-24 15:40:24 UTC
I can reproduce, it's a libvirt regression. I've pinpointed the issue, patch forthcoming
