Cold starting the freenect driver produces no images

This can be repeatedly produced on laptops running Ubuntu 12.04 Precise with freenect_stack-0.1.1 over USB 3.0.

Whenever the laptop is booted up, the first run of the freenect driver fails. Subsequent runs work as expected. This might be an upstream issue.

Reproduced this error on freenect_stack v0.2.0 over USB 2.0 as well.

Error shows up during first launch after every reboot even if the device is left plugged in.

Some basic debugging shows the same error as here: OpenKinect/libfreenect#307

I see a lot of invalid magic statements. The ROS side of things seems to work exactly as expected. The first time the driver is run, there are a lot of Invalid Magic XXXX calls.
