Does inputSingleScan() depend on the device or not?

Hi,

I have an NI USB-6501 device that I use to talk to the DAQ toolbox on Matlab.

My script is used to read the bit changes on the device input port by using inputSingleScan(). I would want this to be as fast as possible, however, I found that it takes ~5ms to finish the scan. Does the execution time of inputSingleScan() depend on the DAQ device I use, or does it take about the same time, regardless of the device?

Thanks!
