I don't think you will be able to use DAQmx with MCC USB-ERB24. You need to run InstaCal (the driver from MCC) to install the USB-ERB24 and obtain a board number for this device (and build your application with the MCC VIs).

I only have LV2009 and I am not able to open your USB_ERB24_test.vi.  The attachment is for USB-ERB24.

After downloading the MCC DAQ CD, please install ULx for LabVIEW which shall be prompted by the installer. After doing so, you will find MCC vis under Functions Palette>User Libraries>UL Extensions. There you will find all the VIs for creating tasks and performing operations upon the created task, similar to DAQmx. I am attaching a vi similar to the VI you had submitted using UL vis.

For the device you have mentioned DAQmx cannot be used and it would not recognize the device. So, you have to use the ULx VIs inside LabVIEW. And for O/P click upon the create channel VI, and select Digital output. Also add UL write after UL start and write the value which you want to output. You have to use ULx for the process, DAQmx will not work.
