Issue Details

Currently, when I plug a USB device into my computer, Measurement & Automation Explorer (MAX) or SignalExpress starts up automatically. How do I prevent this?


For National Instruments USB Data Acquisition Hardware: 

The NI Device Monitor is a service that will launch certain NI software if a NI USB device is plugged in and detected. This may be undesirable when distributing applications with the MAX configurations already included.

To disable the automatic startup of NI software, in the Windows taskbar notification area, right-click on the NI Device Monitor to get to its shortcut menu and select Clear all device associations. This closes all of the service's references to any USB devices that are currently plugged in.  Also, uncheck the Run at startup option in the shortcut menu of NI Device Monitor option to disable the service upon reboot.

The NI Device Monitor can be started again by navigating to Start»Programs»National Instruments»NI-DAQ»NI Device Monitor.

For USB Test and Measurement Devices (Windows 7 Only):

  1. Navigate to Control Panel»Hardware and Sound»AutoPlay to run the AutoPlay utility.
  2. Scroll to the bottom of the window to the Devices section.
  3. Under Test and Measurement Devices, change the selected option from "Control Using LabVIEW SignalExpress" to "Take no Action".
