problem in daq.getDevices

Hi, I'm using NI PXI-4496 and PXI-6711 as measurement

chassis: PXI-1042Q embedded controller: PXI-8106

and when I code daq.getDevices then there

'no data acquisition devices available' (I'm using MATLAB 2014a)

I don't know what's the problem. DAQ toolbox doesn't support my device?

please help me
