what driver i have to install

I use Matlab R2009b and have some problems with data acquisition.

I connected a National Instruments cDAQ-9172 chassis via USB and plugged in a NI-9234 analog input module. To acquire data I used the session-based . Everything worked fine.

But then, when I wanted to use Matlab toolbox to acquire data.the only device that was shown is my soundcard. Why did not appear the cDAQ-Chassis there?

I've installed nidaqmx 9.5, what version of matlab i have to use?

The session based interface was not supported until R2010b.

Also, not all devices were supported in R2010b; each release adds support for more devices. It appears the NI-9234 can be made to work with R2011a; see http://www.mathworks.com/matlabcentral/newsreader/view_thread/301239

I would have to research to be sure, but my vague memory is that R2010a is the first version that supported cDAQ at all in any form.
