USB RF-AP command to id acceleration sensor

Hi guys,

Happy new year! How are u doing?
Unfortunatelly, i'm taking some days at home, and  i'm without my hardware here to quickly test some ideas, and i need to answer a question: we are working on a project using movement pattern recognition, and we have different chronos-430Mhz models, and consequently, we have VTI CMA3000 and BOSCH BMA250 accelerometers.
In your experience, is there any command, such as a model type, serial number range, "anything" id.... which can help to differentiate between those models? 
Well, why do I need to do this? It's because, axis orientation and polarity is diferent between then, and I need to automatically correct them before reporting it to upper software layer...
Thank you guys, and happy codding and hardware designing this year!!!!

    Fernando,

    What exactly are you trying to differentiate, and how are you trying to differentiate? If you are trying to differentiate between MSPs, and only have a handful of devices, you could program a unique "device ID" into a certain location in memory. Then your software could just reference this location to determine which device you are using.

    Hello Mike,
    First of all, thanks 4 your reply.
    I'm trying to differentiante between the accelerometers that comes with ez430-chronos.
    In the beginning, they had come with VTI Tech CMA3000, and now they are coming with Bosch BMA250, because VTI has discontinued its sensor.
    I have users running tests with different models and the software asks the USB access point for acceleration samples and receives them in different sequences, and polarities.
    I'm trying to somehow differentiate the sensors and make them "the same" to my application..
