Is there a function similar to 'rehash' for Data acquisition toolbox?

3 views (last 30 days)
Using the data acquisition toolbox session based architecture, the list of devices is stale until you restart matlab. I was looking through the documentation and didn't see a function that forces matlab to check to see if you had added/removed a data acquisition device. daq.getDevices fails to show a newly added device.
Also, is there a function that checks to see if there are any stray sessions left in memory?

You could try
instrreset
daqreset
If those do not work for you, then NO, restarting MATLAB is the only documented solution.
