commit 7dbbd4330fbb263371cc829d95ef3f18c31b21dd
Author: Hans de Goede <hdegoede at redhat.com>
Date:   Tue Oct 9 00:08:05 2012 +0200

    usb-redir: Fix read error handling depending on SpiceUsbDevice == libusb_device
    
    This has not been true for a while now, but since getting an error return
    from usbredirhost_read_guest_data() is rare no one has tripped over this
    sofar.
