Error -200946 occurred at Untitled 1
Task could not be started, because the driver could not write enough data to the device. This was due to system and/or bus-bandwidth limitations.
Reduce the number of programs your computer is executing concurrently. If possible, perform operations with heavy bus usage sequentially instead of in parallel. If you can't eliminate the problem, contact National Instruments support at ni.com/support.
This error can occur for a number of reasons. Typically the USB bus is a shared resource for many laptop and desktop computers, due to this, the bus can have a lot of activity. On top of this the USB bus communication can be dependent on other process with higher priority. It is also possible that your application is trying to write to quickly to the device. As USB is not a deterministic bus trying to push high data throughput's can result in this error.
If you're using a virtual machine, refer to the article Are NI Products Supported on Virtual Machines (VMs)?
The error happens because the communication bus is not responding as fast as needed.You may look to modify the priority that you are assigning the USB bus, however that may vary given your CPU and OS.
