If you are a developer of Kinect applications and you make use of Microsoft Kinect SDK, OpenNI, OpenKinect and others open source frameworks, certainly you already faced the scenario where you had to uninstall a USB driver and install another to make use of different framework. That is a pain and a wasting time.The good news is that there is a good work done by Tomoto where it is possible to install OpenNI and Microsoft Kinect SDK USB driver in the same machine. This installation enables the use of OpenNI, Microsoft Kinect SDK or both at same time. In other words, you can use calls to both libraries in the same application enabling your app to make features from both frameworks.Lets see how to install and run this bridge.In my case, I did use the latest version of frameworks. So I will make reference to those versions but maybe you can get success using different version.You will need download de packages. You will find 32 and 64 bits of these frameworks but even using a x64 machine (that is my case), I suggest you to install 32-bits package to avoid problems. I have seen some comments that OpenNI 64-bits does not work properly. Any way, go ahead and if you get success installing 64-bits I would be glad if you could share this experience with us.OpenNI 1.5.4.0Download unstable version of OpenNI from http://www.openni.org/Downloads/OpenNIModules.aspxGo to Downloads > Open Sources and get unstable from https://github.com/OpenNI/OpenNI/tree/unstableNITE 1.5.2.21From OpenNI site go to Downloads > OpenNI Modules and download NITE from there. You can select source files or binaries if you prefer no wasting time compiling source files.USB Kinect Sensor 0.93Go to https://github.com/avin2/SensorKinect and download the latest versin of unstable USB driverMicrosoft Kinect SDK 1.5 fromhttp://www.microsoft.com/en-us/kinectforwindows/develop/developer-downloads.aspxOpenNI+MSSDK bridbeGo to Tomoto s website project and download the bridge projecthttp://code.google.com/p/kinect-mssdk-openni-bridge/Note: If you still don't have Python in your machine, go to http://sourceforge.net/projects/pywin32/files/pywin32/ and download the Python package to your machine.Now, lets install the packages.Before we start, it is recommended to uninstall older version of OpenNI/NITE and USB driver.Unplug Kinect device from USB portInstall OpenNI and NITE.Install the OpenNI USB driverPlug Kinect device to USB portIn another blog, I already showed what you will get from Device Manager view when plug Kinect to usb portTest if you OpenNI installation is ok running a sample app like NiUserTracker or any other.Unplug Kienct device from USB portInstall Kinect for Windows SDK. During installation I noticed that Microsoft installer does not allows change the installation directory. I hate to install app in C drive so I ever try to change to a different drive.Needless to say that the installation of Microsoft Kinect SDK is much easier thatn the installation of OpenNI. In the same way, work with MSSDK is also easier thatn work with OpenNI framework.Install Kinect Developr ToolkitPlug Kinect device to USB portYou will get something like the figure below in your Device ManagerNote that the node name is PrimeSense but the sub-nodes are from Microsoft.Go to Tomoto's website and download the bridge packageGo to your msdk-openni-bridge directory and run install.bat program.
