matlab does see my usb-6211

[matter]

My USB-6211 is working fine but my matlab program won't see it. I've tried commands such as

> daqhwinfo('nidaq')

and

> ai = analoginput('nidaq','Dev1');

but it says it canb't find and corresponding DLL.

anyone have any clues?

I've got one of those boards and it's working OK.  What version of NI-DAQmx do you have installed?  What version of MATLAB?
