Generic USB control question

[Tim_C.]

Does anyone know if this information would apply to talking to any USB device?  I am assuming I would need to use the RAW format to talk to a device that does not meet the instrument USB communication standard.

1.  I want to plug a usb based microcontroller dev board into my pc

2.  Load the drivers that windows requests

3.  Use a utility to acquire whatever i.d. information I need from the microcontrollers USB i.d.

4.  Then use labview to simple send a text string or numeric string from the PC to the microcontroller.

Best Regards

Hey Tim C.
The forum that you linked will indeed allow you to use VISA commands to control a USB device. The inf file created will associate your micro-controller and NI-VISA together. From this, you can use LabVIEW to send commands that the controller will recognize to obtain information about it. I would recommend using one of the VISA example programs, such as the USB RAW - Control.vi 

Hope this helps
