Not able to read DataLogic Scanner, Device is null with Windows 7 and Windows 8.1 #68

Dear friends,I need your immediate help.

My Scenario : I am using DataLogic Barcode SCanner to read QR Diagram using  
JavaHIDAPI.I am able to read the Other USB Devices like USB HeadPhone.

But while trying to read the DataLogic Scanner,the Device comes NULL. I used 
the hidapi-rw-1.1jar provided by AngryElectron as a patch.

But it Reads other USB Devices and not the Scanner. DataLogic Barcode Scanner 
device works as a Hid device as well as a Hid Keyboard device. i am able to 
list the Scanner device and get its PID and VID perfectly using JavaHidApi. 
Only ,the device does not open while trying to read the device. HIDAPI is in C. 
I wanted the solution in java. Here, the JavaHidApi also fails to open the 
scanner even after applying the patches.

Please help for the same how can i read the Data Login Scanner.

Let me know if something more on the requirement is required.
