I experienced the exact same problem, a formerly working USB usage
by the virtual machine suddenly caused this assertion to abort
qemu-kvm 0.15.

Looking only briefly at this assertion and the surrounding code,
I found that I did not understand what it's good for, so I removed
the assertion, re-compiled, and - voila! - qemu-kvm 0.15 now works
with the USB device as good as before.
