Reading a NI-USB-6008 from Unity3D

Hi, I'm having trouble loading "NationalInstruments.DAQmx.dll". Unity doesn't work well with non managed dlls and that one is mixed (native for Unity).
I found a similar thread here https://forums.ni.com/t5/Measurement-Studio-for-VC/Problem-with-using-DAQmx-library-in-Unity3D-C/m-p....
Now the guy in the thread ended up using UDP messages to "read" the values needed, is there a way to compile "NationalInstruments.DAQmx.dll" to be managed? Can I read values using any other dll? Has anyone integrated a NI product with Unity directly, with no UDP messaging?
NationalInstruments.DAQmx.dll is a managed .Net assembly but it contains also native (target specific compiled binary code) to interface to the actual driver, which is in the form of compiled native DLLs that then interface to the compiled kernel device drivers.
These compiled DLLs are pretty extensive and a complete reimplementation in .Net C#, in order to make it not contain native CPU instructions is as likely as hell going to freeze over. So basically never!
If Unity 3D really can't deal with assemblies that call into binary DLL's, then I'm very pessimistic that you can ever use DAQmx with it directly! The remote method that you found, where you communicate with a separate process through Inter Process Communication channels that then remotes the IPC requests to the binary DAQmx API is about the most promising solution there is.
