hi all,

Recently, I try to use qemu's monitor commands add/del hotplug disk.

add device use:
1  drive_add 0 file=hotplug.raw,if=none,id=usb_disk1
2  device_add usb-storage,drive=usb_disk1,id=usb_disk11,removable=on
and del device use:
3  drive_del  usb_disk1
4  device_del  usb_disk11

but when command 4 the qemu allways "assertion failed: (obj->ref == 0)" receive SIGABRT.
sorry to tell you that I used qemu-1.2.0 .
and I try to use usb_add/usb_del, but it always tell me use error.
