qemu system emulator crashed when using xhci usb controller
I am testing usb-bt-dongle device on xchi host controller, and found
that the qemu crashed directly with an assertion failer.
Here is the information to reproduce the crash:
Qemu git revision: 9b2e891ec5ccdb4a7d583b77988848282606fdea

VM image: https://people.debian.org/~aurel32/qemu/amd64/debian_squeeze_amd64_desktop.qcow2
CommandLine: qemu-system-x86_64 -M q35 -device qemu-xhci,id=xhci -enable-kvm -device usb-bt-dongle -hda ./debian_wheezy_amd64_standard.qcow2
Error message:
