[ovirt-users] nec-xhci: Win7 guest no response after ejecting usb storage

Hi folks, It's observed that win7 guest will become no response if i eject usb storage "Eject MiniKing" the last screen after i clicked "Eject MingKing": After that, i have to reset the guest. I wonder if it's a known bug, if not any idea to disable this "Eject" . Thanks Zhijian
