When I follow the readme instructions and try to run the sample code I get a null pointer exception if there are any devices connected via USB. It comes from comm.cpp:474 when trying to dereference nxtPtr:
nxtPtr->getDeviceInfo(name, bluetoothAddress, signalStrength, availableFlash, status);
Unhandled exception at 0x003BF10A in ConsoleApplication4.exe: 0xC0000005: Access violation reading location 0x00000000.
EDIT: I'm running 64-bit windows 8.1 and programming with Visual Studio 2013
