Hi Gerd,

at first, guest could recognize this usb storage, but failed after re-enable. So I think it may not be same as bug 949514.
Comment 5 Gerd Hoffmann 2013-10-29 13:47:33 UTC 
Fix for bug 949514 is in qemu-kvm-1.5.3-7.el7 now, can you retest please?
Comment 6 Xu Han 2013-10-30 01:48:09 UTC 
Retested on windows 2012-r2 guest with qemu-kvm-rhev-1.5.3-10.el7.x86_64, and not hit this issue any more.
According to above test result, please close this bug as duplicate of bug 949514.
