First: Thank you all for sharing your information! Without it I would have had more headaches with getting to work the setupapi functions in LabView. That's why I uploaded a lbb for debug and a working USB-Devices_SetupApi_Properties.vi (LabView2014). So others can have advantage of it and having less headaches for using setupapi in LabView. Best regards... Update: Added disable and enable device in USB-Devices_SetupApi_Properties2.vi USB-Devices_SetupApi_Properties.vi SetupApi_Debug.llb USB-Devices_SetupApi_Properties2.vi
