shouldn't it be possible to find "repetition" when taking images - if feasible ? It should be possible to at least identify (even with fuzzy start and end) "data blocks". Once data blocks are identified the "stuff inbetween" should be most interesting to identify what happens. Given that nothing happens in "idle state", this should identify the communication from end of image acquistion to "next image". Theoretically replaying that should trigger a new image acquisition.


The key seems to be understanding what exactly is going on.

likely, there are more recent hardware, software solutions but ...


Step 1: get dataHardware loggers:

TotalPhase Beagle 480

OpenVizsla –http://openvizsla.org/


Software loggers:

BusDog – Windows USB filter driver http://code.google.com/p/busdog/



Step 2: understand data

Download/extract TotalPhase Data Center for your platform:http://www.totalphase.com/products/datacenter/


Get USB trace from someone who bought a Beagle 480:git clone git://github.com/adafruit/Kinect.gitIOpenKinect/USBlogs/enuminit.tdcwith Data Center
