USB passthrough stopped working

[VISEUR Eric]

Hi,

I've just reinstalled a computer with F20 and virt-preview and noticed USB passthrough doesn't work with QEMU/KVM.  I add the device using virt-manager.

·         The device indeed appears in the XML declaration after I add it;

·         Qemu instances are created under the qemu user;

·         Qemu.conf wasn't modified;

·         The device remains owned by root;

·         The VM libvirt log signals a libusb error: libusb requires write access to USB device nodes.

Is it a known problem ?

Thanks in advance.
