PCI-6229 not recognised by Matlab R2011b

I was using the PCI-6229 NI card for analogue and digital IO in combination with Matlab R2007b this was working fine. Then I wanted to use also the counters available at the PCI-card. I found out that this was not possible in R2007b, but it would be possible in R2011b. So I installed the new Matlab version. Then I found out that I needed new NI-DAQmx software too. So I installed the new NI-DAQmx software (version 9.2.3).
However when I now run: >> info=daqhwinfo('nidaq')
info =
AdaptorDllName: [1x68 char]
AdaptorDllVersion: '3.0 (R2011b)'
AdaptorName: 'nidaq'
BoardNames: {1x0 cell}
InstalledBoardIds: {1x0 cell}
ObjectConstructorName: {0x3 cell}
>> info.BoardNames
ans =
Empty cell array: 1-by-0
My PCI-card isn't found.
What should I do?

Can you see your device in NI Measurement and Automation Explorer? Until you see it there, it can't show up in MATLAB.
To use the counter/timer support, you'll need to use the new Session based interface. You may want to port your analoginput code over as well. There's several examples/demos showing the new counter/timer support

Hi Rob,
Thanks for your reply. It seems that I neglected (I can hardly imagine) to reboot my PC. After a restart, Windows popped up with the message "found new hardware" and my device was available in NI Measurement and Automation Explorer and Matlab.
Kind regards,

I am having a problem accessing my DAQ Card (NI PCI 6229) with matlab 2007b. I also, updated my driver software. Wondering if you tried to run matlab 2007b on your card with the updated software and if it worked? Note I am using windows 7.

Hi Teresa
As I mentioned in my first question:
1) I was using the NI PCI 6229 card for analog and digital IO witch Matlab R2007b and the NI-DAQmx driver of Labview 8.2.
2) I updated to Matlab R2011b and NI-DAQmx 9.2.3.
Both situation worked fine (after some troubleshooting).
I never tried Matlab 2007b in combination with NI-DAQmx 9.2.3.
I was using XP.
