In addition, USB-6008 is only officially compatible with DAQmx (previously, the plaform was Traditional DAQ). You would need Traditional DAQ to work with CVI 5.0, but the USB-6008 doesn't officially work with that.
Someone here might have an alternative solution, but though it seems you need to use CVI 5.0, is it possible to upgrade this?
