Is it possible to stream from more than one U3 at a time? I have code which works fine with one U3 connected, but when I connect a second, I get lots of exceptions (re)starting the stream, or data from just one U3. I have already tried reducing the sample rate for each U3 to half of what the application can deal with when only one U3 connected. This is a c# application.

There shouldn't be any issues streaming from multiple U3s from a driver/hardware standpoint as long as everything is set up correctly.  The only potential limitation would be if you are streaming at really high speeds you might max out the USB communication for a single port (if they are all using the same hub), but my intuition is that this would only happen at very high stream speeds.

 

If you send your project to [email protected] we could take a look at the code for you.  If the error is reproducable enough we can typically figure out the issue pretty quickly.
