Description of problem:
Attempt to use USB pass through device in Fedora 16 results in shutdown of entire qemu-kvm process.  Problem doesn't appear to be kernel related, as a proper shutdown happens and gdb reports no exception

The device in question:
USB 0cf3:7015 Atheros (TP-LINK TL-WN821N V3)

The devices module, or device drive was blacklisted, so that it is not in use before virtual machine is launched.  (i.e. /etc/modules/

SELinux is disabled.

Module appears and loads fine under the virtual machine.  However, when an attempt is made to connect the virtual machine to an access point, the entire qemu-kvm process quits.

The log of the virtual machine displays:

qemu-kvm: /builddir/build/BUILD/qemu-kvm-0.15.1/hw/usb.c:336: usb_packet_complete: Assertion `p->owner != ((void *)0)' failed.
2011-12-31 19:23:51.814: shutting down

Version-Release number of selected component (if applicable):

Fedora Linux, with Linux 3.1.6-1.fc16.x86_64 and Guest.

Although, same thing happens regardless of kernel version.

How reproducible:

1) Assign htc_ath9k to black list so it doesn't load, or unload it.
2) Insert USB 0cf3:7015 Atheros (TP-LINK TL-WN821N V3)
3) Start the Fedora 16 3.1.x kernel.
4) Boot into KDE desktop.
5) Click on the AP in the Network Manager, my example required WPA2 password.
6) Type in the KDE keychain password.

Steps to Reproduce:
1) Assign htc_ath9k to black list so it doesn't load, or unload it.
2) Insert USB 0cf3:7015 Atheros (TP-LINK TL-WN821N V3)
3) Start the Fedora 16 3.1.x kernel.
4) Boot into KDE desktop.
5) Click on the AP in the Network Manager, my example required WPA2 password.
6) Type in the KDE keychain password.
 
Actual results:

qemu-kvm exception
qemu-kvm: /builddir/build/BUILD/qemu-kvm-0.15.1/hw/usb.c:336: usb_packet_complete: Assertion `p->owner != ((void *)0)' failed.
2011-12-31 19:23:51.814: shutting down


Expected results:
Connection to the AP for the Guest with no quitting.

Doesn't appear to be a kernel problem otherwise I would expect a exception in gdb.
