At first glance I see "-machine pc-1.2,accel=kvm,usb=off" and then
"-device nec-usb-xhci,id=usb,bus=pci.0,addr=0x5"... I'm not sure if
those should be used together.
Can you look in your libvirt logs from before the upgrade to see if it
was using the usb=off option before?
@kraxel-redhat do you know if that's a legitimate set of options?

Title:
USB Passthrough is not working anymore
Status in QEMU:
New
Bug description:
After upgrading from Ubuntu 14.04 to Ubuntu 14.10 USB passthrough in
QEMU (version is now 2.1.0 - Debian2.1+dfsg-4ubuntu6.1) is not working
any more. Already tried to remove and attach the USB devices. I use 1
USB2 HDD + 1 USB3 HDD to a virtual linux machine; 1 USB2 HDD to a
virual FNAS machine and a USB 2camera to virtual Win7 machine. All
these devices are not working any more.
