I want to generate 5V on D+ of USB of lap. 

Can I use Daqmx, Visa Control Out, or any thing else?

Khaled88,

 

You cannot control the 5V USB power line with VISA commands in MAX. This is a bus standard and the USB port will always port out +5V. You could wire the 5V output into a relay and control it that way, but you will not be able to toggle this line on/off with any NI software.
