Hi, You can use multiple Kinect to capture  Image Stream Same time.

However, your initialization is  second Kinect is failing because the reason could be  both of your Kinect device connected in a single USB Controller.   Kinect devices might not work reliably when they are connected to the same USB host controller .

While developing application using multiple Kinect, make sure devices are connected with different USB Controller and  both are plugged in with external power.

Just Checkout the answer in one of the forum post, http://social.msdn.microsoft.com/Forums/en-US/kinectsdk/thread/58644472-25ce-4378-aeab-424307440616/#da320604-885a-4cb0-9ad8-6ec187dec2b7

 

Here is a sample application developed using multiple kinect device

Hope this will helps !
