How can I write/read to/from a usb thumb drive in LabVIEW

[jmax007]

I have read through a number of tutorials and help information, but I cannot seem to figure out how to do this.

I have created a driver for LabVIEW to recognize the usb drive, and I can find it using the "VISA Interactive Control", but that's as far as I can get.

How can I simply write a small file to the USB drive and read the same file back? I am just trying to do some verification testing.

(using LV2009) 

Thanks

I don't understand why you are messing around with VISA. When a thumb drive is attached to a pc, the normal windows driver will make it appear as an additional drive and you can write and read to it with the regular file I/O functions. There are been several posts on detecting the new drive designator.

Of course..........

I knew that I was looking at this in a far too complicated way.
