At this time, DASYLab only works with NI hardware via the traditional NI-DAQ interface. Any board that is not supported via NI-DAQ will not work with DASYLab V8.
The data sheet for the USB-9215 says:
USB-9211 and USB-9215 devices each come with a ready-to-run
data logger application that acquires and logs up to four channels of
analog data. For more functionality, the NI-DAQmx Base driver
software is a multiplatform driver with a limited NI-DAQmx
programming interface.
This says that it is not supported via NI-DAQ, and is not currently supported by DASYLab.
We are actively working to ensure DASYLab's support for the DAQmx interface - watch for updates of the software!
Please note that new driver support, such as this,
will require an upgrade to the released version of DASYLab. It is not possible to update V7 or earlier with the changes required to fully support DAQmx.
